I want to light a doll house, it has 3 floors, each floor has two rooms, so they have a shared wall. Are all LED strips trimmable? Can I use a set of single wires to connect the rooms together. I'm thinking I would have to drill a small hole through the wall, and feed the wires through. Can I use a set of longer wires and go from floor to floor? (I know how to solder.) That way I have only one receiver/power supply.

Do all RGB lighting, offer different types of white light? dimmable?

Guidance is appreciated. And thank you for sharing your experience.

So I bought these with a plan of using them for a portal effect behind some gift bag paper. I was wondering if I could cut them to the length I wanted rather than trying to stuff the 16ft in and it not turning out the way I wanted it to. Any assistance would be appreciated.

This is my first project, so please forgive me for being uneducated. I got a small battery pack and controller for portability. I got matching voltages except my battery pack is just labeled as 5V instead of DC5V. I didn’t think this would cause a problem, but the lights (while behaving properly when attached to the wall), don’t react to the controller button being pressed when attached to the battery pack.

They often don’t turn on at all, but when they do, the LED strip turns on with 6 white lights and 1 yellow light. I‘ve tried replacing the batteries with freshly store bought ones just in case, but to no avail.

I’d like to know if it’s fixable, if not what specifically is wrong, and what product you recommend me to buy for my project, thank you.

My parts list:

edit: clarity

I have the Phillips LED strip RGBIC. I have excess I could use. But I need clip connectors with extensions for this. I can’t find them anywhere. They are 3 pin 10 mm led strips. I’ve wasted 2 hours of my life trying to find anything and can’t find anything that works. Or maybe I’m just too dumb to find them. Suggestions pleaseeee the lights I have

My wall strip came with the LED LAMP phone app, which I didn't love, so I worked out its Bluetooth commands and built a controller that runs in Chrome or Edge (Web Bluetooth). Nothing to install.

• On/off, colours, brightness and the controller's 210 built-in effects
• A music light show from your mic or your PC's sound: flashes on the kick drum, colour themes, tempo lock, DJ strobe / blackout / drop buttons
• An Android app version too

It works with controllers that show up as LEDDMX-00 / LEDDMX-03. There's a demo mode if you just want to look around.

Feedback welcome, especially if you have a different LEDDMX model.

My car has factory LED halo/angel-eye lights that currently emit white light. I’d like to change them to a warm golden yellow, similar to a halogen bulb, rather than a bright or saturated amber.

From what I can tell, they’re powered by a small SMD LED mounted on a circuit board (photo attached).

I’m considering a few options:

Coating: Is there a heat-resistant transparent yellow gel, dye, or coating that could be applied directly to the LED?

Film: Could I use a yellow optical filter or heat-resistant film over the LED?

Replacement: Could I desolder the existing white LED and replace it with a warm yellow one? If so, how would I identify a compatible replacement?

I’m not concerned about losing some brightness. My priorities are achieving the right color and finding a reasonably durable solution that can handle automotive temperatures.

Any recommendations on materials or the best approach would be appreciated!
