that´s my point!
maybe some of the other lumis owners can provide some numbers, or when they had to change their lamps?
Sure. I got one of the very first Lumis Host units. My first lamp wasn't nearly as bright as I had hoped. I got it in May of 2009. Initially, I was only getting 603 lumens on the lowest power setting. Then, someone discovered that using HDMI input # 3 on the Host resulted in a brighter picture. Doing that gave me 742 lumens in the lowest power setting ( and about 18 foot lamberts off my screen ).That was back in Feb. of 2010.
At some point I measured -
220 watts = 636 lumens
250 watts = 717 lumens
260 watts = 742 lumens
At 442 hours with 270 watts I measured 852 lumens. 4 - 14 - 2010
I have other measurements, but I wasn't good about writing down lamp hours. I was more concerned with it being too dim and time to change the lamp - hours be damned ( probably from my days of owning an Optoma H79 - damn things were dim at 370 hours !! ).
I got a new lamp on 7 - 28 - 2010.
At 4 hours, with 230 watts , I measured 1051 lumens !!
At 745 hours with 280 watts, I measured 860 lumens.
On March 6th I decided to take my current lamp out and save it for a spare, and try installing an OEM lamp in my first housing, since that lamp is too dim for my tastes anyway. It was easy. So far I have only measured the initial output - 260 watts = 1076 lumens. The lamp seemed to actually get a little brighter once it had a few hours and settled in. I'll try taking a measurement tonite if I watch anything.
That's all I've got. If you need a new lamp - call me - I might have a nice surprise for you !Edited by Craig Peer - 6/6/13 at 12:01pm
