So far so good now that the elctrician was able sort out the wiring issues as my wiring was not represented in their diagrams. What they did recommend DID not work. So now that they are working they appear to be the same brightness as the old bulbs but respond much faster and do not produce hardly any heat. If anything changes I will let you know and will probably end up ordering more.

Good but not as bright as we were hoping them to be. At times it makes it difficult to see if it's too dark.

Nice flashlight for the price but not quite as bright as purpossed.

Seems well built and will be handy to have around, but not terribly bright.

I have to give it a 3 star because the light is not as bright as I expected.  It could be because of its small size.

Just got my light haven't used it yet but it's not nearly as bright as I had anticipated. There is no way of telling how many lumens or anything. I bought it with the intention of using it for ice fishing as well as in the ocean in Florida and maine. We shall see how it performs.

It's fine and throws pretty decent light, but I thought it would be much brighter based on reviews.  Still, it's good for the price and arrived much sooner than anticipated.

Brighter by far than the Army issue bulb. However not as bright as I expected and not as bright as flashlights of the same wattage.

i ordered two of these to replace 2 Metal halide light 150 watts each and this light was good but not as bright as the metal halide. Also would be nice if you could pull wire from the back rather from the sides. Would recommend will do another review in a couple of months since today is the first day for the lights.

I would have given it 5 stars but the brightness factor is an issue for me - i was expecting it to be MUCH brighter, but it was only a temperature difference + a little more light. I do prefer the white light to the yellow incandescent bulb color though.

Good lights, but not quite as bright as I was expecting.  I purchased these for a chandelier in my daughter's room, and compared to 40 watt incandecent bulbs, the room is now dim.  The light they produce is very white, but all the light goes strait up.. So don't expect any real light to come from anywhere except the upper half of these bulbs.  Almost like a flashlight, not an all around BULB effect.  Just light in the up direction.

These work very well, but are not as bright as I expected.  I love the MB390 I bought alongside these, and will be getting only that model in the future.

Light output isn't like the sun but so far so good. Can't say about it's lasting quality as I only used it few times but gave me little less than 7 hours at high setting with single charge.

This is a good flashlight but not as good as I was hoping.  I bought it to take with me on an Elk hunting backpacking trip.  The bright is not as bright as I had expected and I couldn't zoom in on a distant object.  I don't really like having the clip located in the middle section of the light either.  I can't tell much difference at all in the lower two settings.  One was just as good as the other.  The light is okay, but just not the "awesome!" that I was hoping for.  I could have been just as satisfied with a cheaper light.  I would get a different light if I had it to do over again.  I'm just a little disappointed in the light for which I had done so much research.  I expected better.

I also got the cone that fits on the end of the light.  I did like this feature in that it was good to light up our tent at night though the light seemed to dim and flicker a little bit after a relatively short time.  It's not a flop, but just a "B+" when I was hoping for an "A+"

works as advertised. Bright but not very bright.

The light produced is less bright than I would expect from a 100 watt clear bulb. The lumens rating is not on the packaging. I use these bulbs in an unheated shop and they are subject to vibration and cold starts. They seem to withstand the cold start and vibration much better that the CFL"s I have been using. Time will tell whether they will meet the 20,000 hour mark.
