Useful or not, they are so bright! It would be different if they were quite dim, but these small LED’s literally light up a room. Mind you, I’m just starting out with mining and have no other place to put my rig other than in the closet with the door left open. If I decide to scale (knowing me I probably will) then I won’t worry so much about the lights.

I suppose I’ll just have to de solder the LEDs and place a cap in there or some other SMD chip to bridge the connection
