mustang guy Posted September 9, 2016 Share Posted September 9, 2016 Here are my thoughts. If the tungsten gets to about 800F dim, the resistance would be 2.85 X 64 watts (800F = 700K), or 182.4 Ohm resistor. A 200 Ohm resistor should work. Something like this Caddock MP2060-200-1% would do. You will need to mount it to a heat sink like one from an old CPU with thermal grease, and make sure it has ventilation. At least with a resistor, you won't have an incandescent bulb glowing. Quote Link to comment Share on other sites More sharing options...
Moderators Youthman Posted September 18, 2016 Author Moderators Share Posted September 18, 2016 I was able to fix the LED for about $10.00. I ended up buying a clamp light and a 25w Black Light Bulb, clamped it behind the cabinet up high aimed at the ceiling. Works perfectly now. 2 Quote Link to comment Share on other sites More sharing options...
JJkizak Posted September 18, 2016 Share Posted September 18, 2016 Of course you know that continuous eye exposure to the black light is not very healthy and can give you a headache. Your eyes cannot control the amount of black light entering them. JJK Quote Link to comment Share on other sites More sharing options...

Moderators Youthman Posted September 18, 2016 Author Moderators Share Posted September 18, 2016 The LED are around the screen. The kids like them on when watching movies so the projector is projecting light onto the front of the screen. The black light is 9' in the air BEHIND the cabinet aimed at the ceiling. And with it only being 25watts, my eyes will never see any light coming from the black light. 1 Quote Link to comment Share on other sites More sharing options...
