Decided to leap over my UV filter idea and go for the gold.
LED tech has finally evolved enough to make this concept possible, and work well.
Going to convert an XL-5100 lamp cage to a 50,000 hr+ LED array.
Before anyone doubts or freaks, no worries, I thought of everything:
Required luminosity, acceptable color temp, sufficient heat dissipation, suitable voltage driver, proper reflector + collimation lens, component spacing and placement. The most difficult task will be to fool the TV into sensing that the ballast and UHP are still present, but I'll figure it out.
It will take up to a month for most of the parts to arrive (they are mostly from China, of course). Then as time permits it will be done.
-no more lamp changes
-instant illumination, no more waiting for lamp warm-up
-absolutely no damaging UV or useless high energy blue/violet emitted whatsoever
-fast power cycling and power outages far less risky
-much more power efficient
-much cooler operating temp (max 50C vs UHP 90C+)
-50,000-100,000 hr sevice life
-same level of luminosity as UHP
-_drumroll please_ *VERY LIKELY* no further degradation of the blue polarizer and panel.
(ahem, no more green, yellow, blue, purple, pink or magenta blobs/hazes to dread creeping up)
...And all for the price of one lousy replacement lamp...
