Here is my current (updated) bulb history as of 4/30/2019
Lamp # 1 (original bulb that came with the projector - No Flap - V1)
1200 Hours = Exploded
Lamp # 2 (JVC official bulb v3 w/ flap)
This one lasted unusually long, about 2800 hours then exploded. It was very DIM by this time however, but I was using it with an HP 2.4 gain screen.
Lamp # 3 = Philips from Ebay - severely DIM at 1100 hours so I replaced (didn't explode), oddly this bulb started out a bit brighter than my next two bulbs.
Lamp # 4 = Philips from Ebay - shutting off automatically at 1700 hours (didn't explode, semi-DIM but still useable)
Lamp # 5 = Philips from Ebay - lasted 550 hours (projector started rejecting it, lamp would work for 10-15 minutes then projector would shut off)
Lamp # 6 = Philips from Ebay - lasted 750 hours (same thing, projector started rejecting with a couple shutoffs, then suddenly would no longer fire up anymore).
Lamp # 7 = Awaiting shipment for OSRAM this time...
Just ordered an Osram for $30 more to see if I can get more usage out of it.
I hope it was really the lamp and not a ballast issue this time (we shall see).
Odd how I originally got 1700 hours out of the Philips, then the last 2 bulbs I got way less.
Probably a coincidence, but you never know.
This might be my last bulb, as I may upgrade soon, it's about time, I've had this projector long enough
Great image, beats everything else for the price (especially in the used market), but looking to step up the game to something brighter (RS400/500 or later).
