This model is meant to give a second life to IKEA LED Light bulb
You can convert it to low DC voltage light. The LED module is made for 30.5 VDC, so these Aliexpress DC to DC step up convertors are suitable for it. The only problem is that its not able to output the full 30.5V but only something around 28.5 V, so you are not able to reach the max brightness.
I made it specifically for the IKEA LED1304G11 bulb, and i have no idea if it will fit different one?
