There are 3 places where it lists the lumen output. 2 say 2150 and the last one says 1550. Is there a difference in output between round and square?

The square ones are 1550. The round ones are listed differently last I checked

I'm really not sure but I bought the square ones and am very very happy with them

Yes that is right. Because of the lumens it guves. Dont get confuse with watts..its the lumens equivalency.

Don`t have the lumen numbers, but we use it to light up a side yard / dog run and it does a good job. Have not had any problems and have considered buying a 2nd unit for otherside of house.

According to most conversion charts I've seen, 1600 lumens is roughly equivalent to a 100 watt bulb. However as others have responded, this light does seem brighter to me - part of that may be that it is rated at a Color Temperature 4000 Kelvin which is a fairly bright white (but not quite daylight) fixture. If you remove the diffuser and look at it while it's on, it's extremely bright. Look at it while it's off and it is very geeky nerdy interesting! :)

For the 30W unit, Zitrades lists the total (R+G+B) output as just under 1300 lumens. I would estimate the white level to be <2700K.

Each 5050 LED is rated ~15 lumens. 540 lm is probably more accurate for this one.

Are you looking for 1500 out of the whole strip? I don't know if you are going to be able to get info like that from typical customer experience. I can say that the ones I got were pretty bright, but comparing them to the 1200 lumen flood light I just bought, I don't think they are as bright as it is nor do they have the same coverage.

Listed as 1570 lumens. However, if you are not using european code housings (sharp horizontal cutoff and deep/wide spread), or hazed lenses, the output won't matter (and may accelerate the yellowing of plastic lenses).

These were flood lights, so they should be 60 degree with 1550 lumens. I don't know the answer to the last question.

According to Nebo's web site, "Output - 157 lumens". I really like this lantern/lamp. No regrets at all in my purchase.

I just looked at this on a different website. The package said it's 157 lumens (cheaper on amazon).

Even though the lumen output is supposedly half a halogen's rated output, I have found the bulbs (I've got seven of them) to be close. I just replaced one halogen today. However, I've been swapping out medium base (screw-in) medium spot bulbs for these GU10 (twist) base bulbs. Because I didn't convert from GU10 halogen reflector bulbs, the light quality may be more noticable different. I hope this helps.

I don't know the lumen output, but the light is for effect only. It is very low light. Also, the batteries do not last more than one season without replacement. I have had these 3 years and that is my main issue.

1700 according to package. I suggest you go to Lowe's: this is a "natural daylight" bulb, nothing special. I bought a 4-pak there for less than seven dollars. Only difference is the ones at Lowe's are 1600 lumens, which is insignificant.

1500 lux equals approximately 690 lumens at a half meter distance at 90 degrees light incidence...look up a lux to lumens conversion to get a sense of it since it's a function of distance and incident angle...i.e. this lamp is a fine desk lamp for all but the most meticulous of tasks...diff temps n intensities...I like it.

As with most led lights you will get a long life out of 1 double A, when you extend the light from wide angle to narrow the beam becomes square not round. Not a problem just different. It is still a stronger beam than my 4 D cell regular mag light....and much easier to carry.

I don't know what the output is, the manufacturer should be able to tell you. However, I will tell you that I've had two to these lights and both failed after roughly 3 months. The first was replaced under warranty. After the second failed I just tossed it and bought something else. The light output was adequate, the fact that two of them had problems had me questioning the quality of the fixture.
