About lumens projectors?

Question

i heard there really cheap, you can buy a 1000 or 1500 on ebay brand new for under 500, it also says bulbs on it last 6000 hours, and they only cost 50 bucks per bulb, this seems to good to be true, i heard all projector bulbs can only last 1000 hours

Answer 1

There may be some confusion here.

Lumens is a measure of projector brightness. A typical Home theatre projector is rated at 1000-1500 lumens, but this is reduced to 300-500 when adjusted for optimum colour accuracy.

Lamps are typically rated to last 2000-4000 hrs (I don't know of any that claim more) but actual can last much shorter (or, presumably) somewhat longer, depending on how they are treated.

Cost vary from about $200 - $500 .... I've never heard of a normal projector lamp that costs $50.

So, any projector claiming 1000+ lumens brightness and with a 6000 hr lamp life @ $50 to replace is either a significant breakthrough (unlikely), will have horrible colour accuracy, or is a scam.
