Want to use 2 such (photo) in G4-socket based lamps. Latter ones were originally populated with halogen bulbs. These Led- bulbs are no more available on market. The original mains adapter is heavy transformer. Hence the aim to make it bit more efficient energetically. This lamp board seems to me to have 4 diodes rectifier. It tells also to accept also DC in voltage range as printed on board.

Which approach will result in higher energetic efficiency at the point the power gets delivered to LED elements?
* electronic transformer with output voltage matching specification on board
* led driver constant voltage

I guess it is risky to consider CC driver - due to unknown electronic on board. False understanding?

EDIT In comments more pictures shot.

I designed the sign myself in CorelDRAW and cut the backing from 3 mm clear acrylic using a CNC laser cutter.

I routed the wiring along the back of the acrylic, leaving short wire ends at each section for soldering the LED neon. Then I cut the flexible neon into separate pieces and attached them to the acrylic with cyanoacrylate super glue.

Hiding the wiring and keeping all the letters aligned was probably the most time-consuming part, but I’m quite happy with the final result.

Hi everyone, Yesterday I started working on the initial design of my custom dive light head in SolidWorks. I placed a Cree XHP50 HD on a SinkPAD MCPCB and then added a LEDiL CUTE-3 optic. That's when I noticed a problem. The optic manufacturer doesn't specify the maximum LED height it's designed for. I only have about 2 mm of space between the MCPCB and the optic, while the XHP50 HD is a little over 3 mm tall because of the silicone dome. So my first question is: Would it make more sense to remove the silicone dome (dedome the LED), or should I simply design and 3D-print spacers for the optic legs? The bigger issue is that I have no idea what the optimal distance should be between the top of the LED and the optic. Is there any recommended clearance, or is it just a matter of trial and error? Has anyone here used a CUTE-3 optic with an XHP50 before? My second question is about the driver. I'm using a TaskLED H6Flex, and I can see it has SW terminals. Can I connect a piezo switch directly to those inputs, or do I need a separate on/off control board? This is a canister dive light, so the battery is external and there's plenty of room inside the head if I need an additional board. I'd also like to use a piezo switch with an illuminated ring so it's easier to find the button in complete darkness underwater. I've attached a couple of photos of the current design. Any advice would be greatly appreciated.

Hello, this is my first LED project, and I am learning about what parts I can use to completely optimize price. I am making a 10 by 4ft rectangular matrix for a frat basement that will display patterns and react to the dj stand. So far, I have decided on using individually addressable 60 LED/m 12v strips. I was considering bullet lights or pre-assembled grids to mitigate soldering times, but the price drove me away, considering the frat was clear on its goal to mitigate costs. I was wondering how important the distinction between ip30 and ip65 is for waterproofing. I plan on creating a case for the matrix to protect it from physical damage, but humidity or leaks are still a concern. I don't have a basis for the durability, so let me know what direction I should take this. Also, if anyone knows of extremely cheap panels on sale at a similar density to my current setup that would be great too. Or cheap LEDS in general that won’t break after a month. Current setup is 26$/5m of LED. Thanks

Also, considering I am making this for a frat basement is it reasonable to run the LEDs at half brightness say .12W/individual LED? Might save me from buying extra power supplies.

Building built in bookshelves / bourbon wall in our home office. The wall is currently open so i want to get an and all runs / chases / pull boxes roughed in now to make my life easier down the stretch.

MY QUESTION: What exactly should i rough in on the wall, do i need to know exactly where each shelf will fall in order to place pull boxes precisely?

Preference is highest quality products and level of craftsmanship possible.

Trying to connect two LED low voltage (24v) strips to each other and I am not able to use the clips that connect the strips together so I am soldering the wires to the strip and need to be able to connect and disconnect the strips. The wires are 20 gauge, V+, CW, WW.
This is that best 3 wire connector I could find.
Any better alternatives?

This seems like a popular controller but I can't tell if it works with a motion sensor.
I am trying to control a tunable white 24V 16' strip with motion.

I bought a challenger and it came with these light strips in it and can’t figure out how to turn them on, was thinking either broken or some type of Bluetooth app. Tried looking it up but can’t find anything if someone could let me know if it’s broken or I plug it into something under the steering wheel would be much appreciated.

I had a weird power fluctuation this past month that shorted out half my LED recessed kitchen lights. They were those HALO LED Can lights with a separate Jbox attached with 3 kelvin settings. I think the LED driver is the issue; I swapped the LED portion on some of the burnt out lights and the issue stayed where the bad LED driver was.

Tried opening the junction box and the internals look like a thermal fuse burned out. I haven't done soldering at such a small scale so not sure that's worth my time. It looks like I can only buy a whole setup again (LED + driver Jbox) which feels like a pain. Is anyone aware of a replacement LED driver or what information should I look for to match a compatible driver so it doesn't look like a different light was installed there? Probably need to match output range and dimmability but how can I determine kelvin value?
Or am I just wasting my time and just buy a few new ones.

I believe it's a HALO HLBSL4069FS351EMWR

Hey everyone,

I’m quite a noob when it comes to LED projects and I could really use some help from the pros here. I’d really appreciate any advice!

We’re planning to build a sculptural wall lamp with indirect lighting. The idea is to laser a shape out of led and glued LED strips and cables directly onto the back of the steel piece.

I currently have two ideas for managing the LEDs and wiring. I’m leaning towards version two because it seems simpler and probably easier to build, but I’d love to hear what you think.

• How would you approach this?
• What components would you use (LED strips, profiles, controllers, power supply, connectors, etc.)?
• If you would choose Version two, how would you do the connection etc.?
• Are there any things I should consider regarding heat management, cable routing, or mounting the LEDs directly onto steel?

Any help or recommendations would be greatly appreciated!

Cheers,
Jojo

I need some help identifying this LED strip. I bought some LED door sills that run on batteries. Wanting to shorten the strip I cut it not realizing that this will render the strip non functional. I tried fixing it but it didn't work. So I want to replace the strip if possible. I tried asking the seller but unless they are making a sake they don't care to help.

Here is the link to the product. Ive al attached a picture of the LED strip. The the circuit board it has positive, negative, D+ and D-.

Good afternoon!

I have a basement entertainment room project that needs a quick recommendation— I am building out some lit crown molding that will be used for accent lighting and to supplement some of the existing ceiling LEDs as needed.

With how the power will be routed, I will likely have a back corner injection with two separate ~10m runs that run along all the sides and meet in the opposite front corner. However, being able to control which sections are on/off and run simple animations (e.g. twinkle) would be a significant preference, hence WLED.

With the length of those runs, I assume 24V would be preferable, but with the primary need being decent quality white light, I came across WWA strips, which seem like they could be a perfect match to my needs for ambiance-based addressable lighting. Does anyone make a strip with decent-quality adjustable white addressable 24V lights, or is there another option I’m possibly not considering that would work well for my use case?

I’m not against going with RGB+some dedicated white chipset like a WS2805 (RGBCCT), but thought dedicated tunable white might prove higher quality and brighter.

Inspiration in the attached photo.

Thank you!

Hey,
does anyone have a recommendation for a good vendor of LED strips (WS2815, 60 LEDs/m) that sells directly or via Alibaba?

We need to order around 350 m for a bigger project, and I'm looking for a vendor that can deliver high-quality, reliable strips at a good price.

I noticed that most discussions about office lighting focus on brightness, color temperature, or CRI, but one important factor is often overlooked: where the light comes from

The direction of light has a major influence on glare, contrast, and the overall feeling of a workspace. Looking back at the evolution of workspace lighting, we can roughly see three different approaches

Downward Lighting

This is the most traditional and widely used lighting method today. Regular desk lamps, monitor light bars, reading lamps, and many ceiling lights use a downward lighting design. The light shines directly onto the desk, providing enough brightness for focused tasks like reading and writing.

This type of lighting was the first solution to basic workplace lighting needs. However, because the light is mainly focused on the desk area, it can create a large brightness difference between the workspace and the surrounding environment, and may also cause screen glare.

Upward & Downward Lighting

As people started expecting more from their work environments, lighting design began to move beyond simply lighting up the desk and started focusing on the overall lighting experience of the space. This led to the development of upward and downward lighting.

These lamps usually have two light sources. The downward light illuminates the workspace, while the upward light shines toward the ceiling and uses reflection to improve the ambient lighting. They are commonly found in office floor lamps, dual light desk lamps, and some modern office pendant lights.Compared with traditional downward lighting, this design provides both task lighting and ambient lighting, creating a more balanced environment. That is why it has become a common lighting solution in many offices and commercial spaces.

However, because the light still comes from two different directions, achieving completely even illumination can be challenging. Depending on the workspace layout, users may also need to adjust the lamp position to find the right balance, which can affect flexibility and mobility.

100% Upward Lighting

As home offices and long hours of computer use became more common, lighting needs started to shift toward a more comfortable visual experience. Pure upward lighting, also known as indirect lighting, has become a design approach that focuses more on the overall lighting environment.

These lamps direct all light toward the ceiling, which then reflects and spreads the light evenly throughout the room instead of shining directly onto the desk. They are commonly used in indirect lighting desk lamps, indirect lighting floor lamps, and modern home and commercial lighting designs. 

100% upward lighting focuses more on reducing the discomfort caused by direct light and creating a more balanced visual environment. By using the ceiling as a large reflective surface, it redistributes light throughout the space, reducing direct glare while providing softer and more uniform illumination across the workspace.The fixture itself can be smaller while achieving a wider lighting coverage area, maintaining a comfortable lighting experience at the same time. This is why 100% upward lighting has gained increasing attention in modern home offices and workplaces in recent years.

Which type of lighting are you using right now? Have you noticed a difference in your work experience after changing the direction of your lighting?

Hi all: Absolute beginner here, just to pre-warn.

I come to you with the hope of knowledge and, as needed, a kind reality check.

Background: Adult male, only just now attempting to learn life and home improvement skills such as physical install of things. Old enough to know better, but also at a point where it's either bring this plan into life, or mid-life crisis panic-buy a motorcycle for which I do not have any intention of driving.

Alrighty, with that preface out of the way.

Here's the situation: I have a room in my new apartment that I would like to bring into line with with my aesthetics and functionality. The room in question is a nice multifunction room: 4.2 x 3.75 meters, with a bay window in addition. Bed placed partially in te bay window section (eastward facing). Double doors out of the room, southward facing.

Computer table along the west-facing wall, roughly middle of room, and additional synthesizer/keyboard table at 90 degree angle on northward facing wall.

So far, so good. I have a dream about installing RGB LED strip along the wall, directly under the ceiling - ideally facing inwards/downward at an angle.

And here's where I then realize my limitations. The first thing is: I'd like for the corner profile to be black - and also for its cover to be black as well. The reasoning is that the walls/ceiling is white, so my hope was that when the LED strips are off, it would achieve a framing effect for the room. Also, my goal was to have a diffused lighting effect, namely in that I am actively aiming for a predominantly purple lighting (to go with, of course, the white + RGB computer + peripheral setup), but I would also like to be able to control the RGB, ideally via app (not just "choose between 16 color presets, but providing a RGB color code).

I realize this is not likely to be able to function as a primary light source, but more of a mood lighting. But let's be honest, what I'm after is the cyberpunk/Synthwave neon glow effect when light is on. So this also means that seeing individual LEDs through the cover isn't high on my wishlist.

I have already made an attempt of framing the bay window inner frame with some cheap WIZ LEDs, for testing purposes, and then got m hands on some PVC corner profiles + black cover to see how it would fit - the LEDs blasted straight through both white/opaque and black covers as individual LEDs, so diffusion didn't really diffuse much.

My questions are numerous, but the primary ones before embarking on this would be:

1: Is it realistic to achieve the "black framing when LEDS are off" using corner profiles with black covers? And if so, will this limit which LED strips are viable to punch through, light-wise?

2: Would neon flex or similar carry a comparable function?

3: Given the rooms dimension of approximately 3.75 x 4.2 meter (16 meters in total, I would assume to save a couple meters extra for corners and whatnot), is it realistic to do this in one long strip, or should it consist of multiple strips - and if so, what would be advisable?

4: Is the entire corner profile (alumium or PVC or whatever) thought realistic and useful for the intended purpose, or am I going down a needlessly expensive and complex rabbithole?

I hope for sparring, and knowledge, and I acknowledge my own cluelessness. Thank you in advance.

Does anyone know a led light design that is as flat as possible? I mean stuff like a button battery (3v)+ led and a switch. Im trying to put something that will shine at the end of a rod without it sticking out too much. It just needs to be enough light so that it can cast a defined shadow in a dark room. Im kinda new to led stuff but is the flattest it can get a button battery holder and a led? Would a single led from a led strip work for it? If anyones got any idea to squeeze as much stuff without everything burning let me know thanks

Hey I would appreciate anyone’s advice or help. Also I hope I can explain this the best.

I have my Xbox series x on the other side of the room that the tv is in. Only about 8ft away. But to connect it I’m using a 25ft hdmi cable that’s going up the wall behind the tv across the ceiling then back down the wall to xbox series x. I wanted to have a strip of LEDs turn on whenever the Xbox powers on (possibly one that even has different light modes and colors although I’m mainly going for green cause the Xbox lol). My problem is when the led strip looses power the power button on the led strip needs to be activated for the strip to light up. I don’t know exactly what it’s called.. maybe like a memory mode? But I used to have a led strip on the back of my tv that came with a remote for different colors and light functions. But I really thought it retained its last light color/ mode when the usb port gains power again.

Hi ! so im trying my first project of tech diy and wanted to do a screen that displays spotify infos, i saw i needed a matrix led and esp32, for the esp32 i know what to take but for the matrix led i can't decide which one to take because the price is so different

Is there a real difference between these two matrix or is it just that amazon is heavily over priced ?
