LED Projector Lamp V.1.0 - Instructables

My first video projector. Ever.

Please visit our website for more information on this topic.

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 T70Muser 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.

Projectors, like TVs, are rarely set up to look their best right out of the box. Look for a picture mode called Cinema, Movie, or Natural.

If you want a big screen, you need a bright projector. Tiny projectors are not bright enough to deliver a big-screen, cinema-like experience.

If you’re not sure where to begin your projector search, we recommend reading about how to pick the right projector for your viewing needs. In summary, you have three important questions to ask at the start: What do you plan to use the projector for? What type of room will you use it in? How big of a screen do you want?

There’s a huge difference in price and performance between a 4K projector designed for a big-screen home theater and a portable mini projector designed to be an everyday TV replacement. Some projectors excel with movies in a completely dark room, while others are better for sports or gaming in a room with some ambient light.

Generally, the bigger the screen you want, the brighter your projector must be to produce a satisfyingly rich image. Once you have a general idea of the projector’s intended use, it’s easier to zero in on a specific choice.
