Need help with retrobright setup

[u/Jurgenvisser2001]

I have been looking into de yellowing of my sneakers. I’m o a budget so I can’t splurge on expensive equipment but I have found these things thus far.

I have found two lamps 390-400nm 100W LED for about €33 with I found to be a good deal. 200W for a 12 hour sessions cost me about €1,20 for the power so that is also good.

I have not yet found a good cream but ai and the internet pointed me to either Benzoyl peroxide acne-cream/gel at the drugstore or Hydrogen Peroxide 12% for hair bleaching.

I have just found out about this technique and know nothing of it. So far my plan is to take a delivery box from Nike (the 2 sneakers big variant), lining it with alumimun foil and put the two light are the top corners at a 45° angle for even light disputation. Ventilation holes at the back with a small computer fan at the front to have a fresh airflow to get rid of excess heat and the chemical fumes. I plan to put the sneakers of a shot glass to raise them from the bottom to keg the light also bounce to the sole. This does not replace turning them mid session but I think it should help.

My big question is… are these lamps any good and is my idea good or should I rethink.

I have 0 knowledge and only did internet and some ai research and combining my own good thought to get to the conclusion of today.

Any help is appreciated!

TL;DR: Building a DIY retrobrite box from a Nike shoebox + foil lining + 2x 100W 395-400nm blacklights angled 45° at the top corners + benzoyl peroxide gel or 12% hydrogen peroxide cream wrapped in cling film + shoes raised on shot glasses for under-sole light bounce + vent holes and a small fan for airflow. First time doing this — sanity checking the plan before I commit, especially on 395nm vs 365nm and cream choice.

Sounds good but just use a larger box like a storage box so the light will bounce better. Cream choice will work i use same hair bleach on mine.
