how many lumens is this projector once it's running on battery instead of power? is it still 500 lumens or does it drop?

I think no difference on lumens according to battery or pwer But i'm not satified with this rojector cause its not very clear on the class room window light

The brightness does not change. It is as good on the battery as it is on direct power.

The projector isn't LED it uses a BL-FU190E lamp. Which has a 6000 hour life. If you do a search on Google you'll see you can buy this lamp assembly for $150 - $180. Still about the most economical lamp in the 2000 - 2500 lumen range.

.25A with the projector turned on; .08A if it's just charging. Measured it with my Kill-A-Watt.

I didn't make any serious measurement but battery power is enough to make around 200 pictures without problem - at least this is what I have experience. A little bit less when you want to make some movies.

According to the label on the wall wart that comes with the projector, the INput is 200mA @ 120V which calculates to 24 watts input maximum. The OUTput is listed as 6 vdc at 1.0 amp which calculates to 6 watts OUTput. Not much. I'm not sure what you want with a timer for . . . the unit has a timer internal set to 4 hours or so. It automatically shuts itself off. That information is available in the description on Amazon. I've had mine awhile now and still enjoy it.

Picture quality is awesome. However- not sure about your setup, but a short throw doesn't make much sense for an outdoor projector. Also not sure about brightness for outdoors, since there tends to be a lot of light outside that you can't control. Probably safer to look elsewhere.

no idea.. still getting used to it. I haven't figured how to adjust size, save moving the projector up close. The brightness and clarity were good. This was my first public use of it. All-in-all, pleased with it.

It's just 500 lumens all the time, but it will eat through your Surefire batteries quickly. At first the light output is immense and blinding, but after probably a month of frequent use the light dims down to around 200-300 lumens...ish. Still an outstanding flashlight!

If you have control over lighting, you only need in the range of 400 to 700 lumens for theater quality footage in complete darkness. Keep in mind that things in your room can reflect light and decrease contrast. I run mine in eco mode + theater settings, so it's well under 1800 lumens. On a side note, the dimmer you run it, the longer the bulb lasts.

Yes you can run the projector without the battery installed, my battery stopped taking a charge after 6 months.

Leah, the lumens are 4000, and the box says the bulb is designed for an extra long life.... I don't know if you can buy a spare with the projector, sorry. :) Hope this helps. I love this projector, it's perfect for me.

Don't be fooled by all the shills for the seller. It isn't even 100 lumens. It's a perfectly acceptable light, just available elsewhere here for $8 for the exact same setup. If you do the math, there is no way that the voltage supplied by 3 AAA batteries is going to provide 500 lumens of light unless there are capacitors involved and then a half second of light.

I've never used the projector over it's maximum distance, but it has worked very well in medium sized conference or meeting rooms. It is bright enough that the room need not be totally darkened. Low lighting in the room still allows for a clear picture on the screen.

I don't know the exact number. But I can say that in a bright sunny room you can't see it. In that same room when it is overcast you can see it fine, but lose a certain amount of dynamic range. And in a slightly darkened room (twilight or early morning) it is perfectly usable.As its an LED based projector it will not be as bright as the bulb variety.....

I would run away from this projector. It is not good and overheats your phone to the point of being untouchable. Look for a 3M projector that connects by a cable and has an internal cooling system. You'll be much happier.

mine works well, the problem i found it is very noisy, i can hear the fen working so it is better for outside or using good speakers, the resolution is not too good either so if u need very detailed image i think u need domething better, but it is the cheapest so if u want something better u should spend at least 500. when i recently bought it i was unhappy because it is hard to project in canvas the reason it is hard it is because you will have to move the projector to get the desired size. all functions work well but i found that i can use lycra and then i made a lycra screen and then i invert the image in the projector and i like it on this way. i hope it helped you

It has 15 lumens at low power (16 hours battery life) and 30 at high power (8 hours battery life). This is not a bright light-- but it is sufficient light for most purposes.
