curretly with my 30W LED i shave standard pc heatsink to fit in pJ box. after 30-40 minute of it is pretty much 50-55 degree. but won't work for 100W LED.

just sharing idea.

If I use a Liquid Cooler and have the Thing outside. It's NOT going to work in my case. I hate seeing extra stuff around my PJ lol

Anyway, I'm gonne see how I fit it all in once done!

OMG, I done it but the Lumens is like about 600

The light Bulb is really bright outside but once you put it in... I don't know where all the lights go

I dunno where I am heading now since it's NOT working the way it should. My PJ seems NOT letting all the lights passes through...

Anyone have this Problem?

Please reply if you do, thankx!

hi,
let me explain something hope that will help you to understand
instead of original lens, in front of LED you have to use collimater lens,
bcoz LED light plate produce scattered light you have to focus all light to one Strong BEAM that one only possible if you put right collimater lens with reflactor.

tomorrow i will post my LED lamp which is 30W LED which is way low, but it is good for experiments. if i would able to take picture of working pj i will post that too.

All you have to do is open you Projector and find the Ballast, under the Board with lots of Screws, LOL

Anyway, just solder the Optocouplers like in the Pix and you are all set. Just a NOTE: I tried the 1st one, didn't do anything, 2nd one = no and then I did the 3rd one... All of them and BANG it worked!

I will install an LED BULB in, after done, I will post some Pix with LED in it and also some helpful info...

Hope that this will help someone...

Also the Manual on Page 19 is helpful:

I used this method on a Sharp XR-10S-L: worked like a charm, just had a bit of trouble getting to the optocouplers. BTW, they are named D7713,D7714 and D7715 in the list in the service manual.
Thanks!

Also works for NEC LT150z. Just look for three PC123 optocouplers in a row.
