Hey guy's. I got my bulb working an hour ago. Pretty pleased with it . Because I dont know much about that stuff (zero). Okay but I got the bulb working, now it's time for the rest.

TFT Screen / Fans.

So I guess I can connect my fans to the bulb? But how can I do that the best?

This is how I connected my 400WHQI bulb. I need to put in 2 or 3 fans and would like to do that with using a PC PSU. I believe it is possible to let the fans run a bit longer than the bulb, (and recomandable) but is that also doable when I connect the fans on the bulb?

Im realy eager to get on with the project so any help/links are great!

There are a number of ways to incorporate a circuit into your scheme. One is using a thermal switch which runs when your lamp circuit is energized and also if the temperature is higher than a set point. Another is simply switching your fans separately. Another is using a timer circuit such that your fans run for a set amount of time after your lamp is turned off. I prefer using a scheme with a thermal switch. There are a number of wiring diagrams available on the forums here detailing almost any option you can think of.

Hm okay, found some good idears in there. Would like to use something like this,


Okay I got a few questions about it, like how can I wire my screen to the same power line as my bulb? Or rather, how can I get everyting from 2 power cables into one?

You'll want your LCD, fans (if they're 12vDC) and lamp powered separately (like in the lower diagram) to cut down on any interference getting to the LCD.
You'll still only have one power cable coming into the enclosure, where it's split off to the various power supplies that are also housed internally.
