To replace 118mm 100w halogen R7S flood light.

100w halogen is pretty poor, with typical Chinese translation you could prob cut that to 50w equivalent.

the issue is those 5050 size leds are just not meant to project light. Best spec on 1 of those 42 leds has a max power of 0.1W, that's with infinite heatsink. With no heatsink, they will fade and die pretty quickly.

So 42 x 0.1 =4.2Watts of light, is about equivalent of 30W halogen
