Even if this thread has started so long time ago, it is still SO GOOD
for anyone that is starting to get into projectors. So MANY THANKS
I for one, I'm not at the beginning, already changed one lamp on one HD projector and got also a second one that does 4K (although by e-shifting) from the same brand (Epson), also with lamp.
But now I was thinking "mingling" here to ask a question:
Why does the producers of those lamp based projectors did not (yet) started to do just a small change, by replacing the bulbs/lamps with LED's?
And until the producers start doing so, can't we do some DIY to get the bulb/lamp replaced with LED's?
I am asking this because I have seen A LOT of LED sources now are available with A LOT of lumens power, and they are even getting smaller and powerful day-by-day almost.
The heat from an LED light source I believe would produce similar or less heat than the bulb/lamp does, and there's already the fan for cooling it down. The power requirements for a LED would be surely less than for the bulb/lamp, so this should not be a problem either (I saw some super bright flashlights which works with batteries, not with mains, so...).
Are there any other reasons than the "business/income" that comes from the bulbs/lams already produced and the factories for them, so ultimately just a "money problem", not an technical one?
So, @Scott Wilkinson
and ANYONE else, what's your input on this idea?
