My first video projector. Ever.
Last year I came across a cheap Toshiba TLP T70M projector on some e-bay wanna-be site over here in Romania. It had no lamp at all but other than that it was operating properly (or so the salesman told me). I traded it for a Shuttle computer I had in my closet and in a few days the projector was delivered. I was surprised that it was in a good condition, I was expecting cracks and scratches, it had none. I turned it on and - predictably - the “lamp missing” LED came on in about two minutes. At this point the projector shuts down automatically. During those two minutes I was able to see the startup screen by looking thru the lenses while holding a small flashlight where the bulb was supposed to be. So yes, it was operating.
I started google-ing all I could find about this projector. I came across the complete Toshiba TLP T70M user manual (it had none when I received it) and that’s about all. At this point I wasn’t really decided what to do, I was tempted to buy a light bulb for this model and use it as anyone should. On the other hand being horrified by the huge price that projector bulb had it was clear I had to find an alternative light source. Me being a LED addict I started thinking about that. It was the obvious choice but the problem will be the light output. The projector’s lamp had 2000 lumens and in “eco-mode” had 1000 lumens. I was aiming for his lower figure as I won’t be using the projector in daylight anyway. So my goal is 1000 lumens of LED light.
Insert a few weeks of random ideas and pointless calculations here. Lazyness, to be more precise.
