Is it bright enough to use in a classroom? (in the past 3000 lumens was the gold standard.. 700 hardly seems bright enough)

Definitely not! This is at bes good for a mobile war room or small presentation rooms with little to no light. I haven't found anything truly portable that comes close to a larg, bright and sharp image. Good luck on the search.

Definitely bright enough. I know what you mean about the lumens but something must be different when it comes to led bulbs cause this one is fast brighter than my previous epson projector that had regular bulb and 2500 lumens? If your worried about it lg does make this same model but s little better and more expensive. This is a really nice very small smart projector. The hd picture is just amazing same with 3d

Yes, as but you need to dim the calss lights.I use it on a daily basis to teach undergradure and graduate students and it serves this purpose very well.

It all depends of how much dark you can get your classroom and how big your screen would be So, you can buy it and adjust the size of your screen accordingly to the brightness in room Some hints: First -This is one of the brightest led projectors yet (even LG PF85U with 1000 lumens is somehow not so more strong, because image seem those they boost with a wite lamp to get more lumens, like acer k530) Second: Led lamps do not get weak over the time like regular ones do, and the light is somehow much less yellow tinted, so one 700 lumens led projector, can be compared with a much brighter regular lamp projector, like a old 2000 lumens lamp one Third: If you want a brighter and much more powerfull projector, that lasts more than 20.000 hrs, specially to use in classrooms, go to the casio signature models, with 2500 to 3000 lumens (white light also). Those casios have not so great color balance, costs like U$ 830 to U$1000, but are the perfect choice for educational issues, and are really realy strong (there is a youtube presentation were a guy uses it's internal laser source to cut appart some plastic garbage, to show how strong is its light source - of course, when iside the projector, its laser is safe and does not hurt anyone - but dont stay staring directly to the light at short distances, as you wouldnt do also on a 3000 lumens lamp projector...)

Yes it will but depending on your expectations. The lumens are enough we are currently using ours for school, it meets the need for the bucks. But if you are in advertising or high definitions is needed for your presentations, probably it will be better to invest in a more expensive model. If your presentations are more in-house I will say it ok, meets the needs and can be seen either in a darker room or with daylight with out any issue.

In a fully dark room, once your eyes adjust then this would work. The lighting it very dim. Sorry I cant give you an empirical measurement in lumens.

Dim lights. It works fine in my living room, circa 150 square feet, with one 100-watt bulb. The image was barely visible in my Sunday school classroom with a ceiling full of flourescent lights on. I had to turn the lights off and let the room just be lit by light coming in the windows. So no, I don't recommend it for use in a brightly-lit room. This projector appears to be intended to watch movies with lights out or dim more than to make business/classroom presentations. It's usable if you can dim the lights or turn them off, but not ideal.

i dont know what you consider to be bright, but it is bright enough to show clearly lit with my room light on and plenty bright in the dark.....hope that helps

This unit is excellent as a classroom projector. It performs very well in a fully lit room, and of of course much better in a darkened room. Images are crisp, bright and excellent saturation. My classroom setup is U-shaped (tables around the edges) and my projector sits in the middle approximately 10-15 feet from the screen. This setup works well for me with excellent visual results. Hope this helps . . . bgs.

I am not sure what the Maximum lumens is, but I can say that it is not terrible bright. Depending on the size of the room it might work, but I don't think I would use it for that. I will say though...it is an exceptionally quiet and smooth fan.

Not enough. Its not the lumens you have to be concerned with but the fall off for distance. These produce very nice light but they are better for fill in on bottoms and middle of plants. Only hps and ml gives real source light. Sure, you could string up 20-30 in a small space, but at that point, your not saving any wattage and your bulb replacement cost is prohibitive. They last about 2-4 months. Check out some of the setups on utube. Good luck Bonnie.

It isn't as bright as i would like it to be. It also requires a certain kind of bulb that doesn't give off a lot of light. It also depends on how big the room is. Hope this helps!

I don't consider it to be too bright. It casts a lot of light behind and up the wall it's plugged into, but just a soft glow away from the wall. It's in our three year old's room after going his first two years with just a very dim blue light, and it doesn't bother him at all. You mentioned a small nursery; our room in about 10ft X 12ft.

I think the answer is somewhere in the reviews and my guess is at least a hundred. I use it in my bedroom to work in bed and it is plenty bright for that. If I look directly into it I am blinded for a few moments. Unless you want to light an entire room, this light should be bright enough for reading, crafting, computering, etc.

We installed it in a classroom and was surprised how good the picture was with all the bright lights on. Also the fan was very quiet. I recommend this projector highly!

I'm using it in my living room area and I would say it would make a bedroom very bright. One thing you can do is use the more expensive lightbulbs that they talk about but I'm using the older version so it is not so bright for me. Hope this helps.

We are using about 5 LED lightbulbs at 40 wts and it is very bright. I chose to use incandescent lights so that it would be softer. I must mention, that with our dining room lights, we can actually control how bright we would like the room. At high, it is very very bright. At a medium setting, it is still bright. Hope that helps.

Hi, I bought this projector 2 months ago and I was worried about the same, my room is really bright, but I have to tell you that image has good quality with natural light(morning/afternoon) I use projector mostly for video games and I can play them with natural light. Obviously, it changes tremendously in a dark room, image is almost perfect. Hope I helped you.

yes, but the screen size depends on the distance of projection. The classroom can not be too bright.

Yeah. Should be ok. But for better n brightness classroom need to be dark. U may not like it in a brighter room with open windows door.
