How bright are these in terms of lumens output or incadescent equivalance?

If measured at the LED, I would estimate them to be around 500 lumens, maybe higher. That is only my guess. Hard to gauge because of the spread of the light. It lights up a decent size area very nicely, unlike a flashlight would. Great for garden areas. I put two of them up in my smallish backyard and it lights the whole area well.

I don't have a monitor to tell how many lumens the LENBO 10W 12v DC puts out. I can say that the visual light is about 3 times brighter then the 20W 12V DC Halogen I replaced. Also the light is whiter than the Halogens. The cost is well worth it. I bought 3 of them for what it cost for 1 at another web site. I only wish they had a 5W because the 10W LED's are just too bright in some areas.

I don't have any metering equipment, but I've seen some descriptions that say they are equivalent to a 50W halogen bulb. You can look at descriptions from various sellers to 'LENBO LW1' to get their ratings. I have them lighting up parking spaces under the building at my apartment complex. Two of them is good enough to light a 4 space bay with just enough brightness to see the locks on the car doors at night. Hope that helps.

They are rated at 900 Lumens - plenty bright - equivalent to a 90WI do not have a light meter to verify exactly-

These bulbs definitely are bright enough. But they are not dimmable. You also need to make sure you don't have space constraints since these bulbs are slightly larger than the incandescent bulbs they replace.

I'm not sure what the lumens are because I bought it for a gift. All I know is that they were bright and my brother in law is very happy with them.

quite bright in my opinion. much brighter than the 75W incandescent it replaced.

It's not a matter of brightness. Both emit the same # of lumens. It's a function of the light spectrum they emit. So it's really an aesthetics question. Some people don't care for "white" that's in the 5,000K range and prefer the "warm" or yellowish light emitted at 3500K.

Beats me, but they're not much brighter than the 40W-equivalent version. They are some of the nicest LED bulbs I've used though. I use a cool white one in the fridge -- it is instant-on, like an incandescent, unlike other LED bulbs I've tried in there.Note about dimming: They don't dim at the same pace as incandescents in the same fixture. In fact, they don't seem to dim at all.

My package says "80 Lumens Max". I love mine. Very bright when batteries are fresh. Just be sure to use good batteries. I use rechargeable and they usually only last me a night or two before the light starts to fade away.

2800 Lumens, 45 watts. They fit in a standard medium base fixture. There is a faint buzz, but it's not intrusive. I have six installed in my garage and only hear the buzzing if I'm listening for it. I suppose it would be more noticeable in other environments, but it doesn't bother me at all.

200 lumens / specs are here:http://shop.ledwholesalers.com/index.php?route=product/product&path=39_85&product_id=247

I feel that the light output on these are greater then regular led bulbs. I use them as backup lights and it gives me greater visibility then stock and regular LED's.

I think the output is about 16,000 lumens -- see ultrasunlamps com --> http://www.ultrasunlamps.com/1798

I don't have any technical information on hand about the comparable brightness, but I can give you my opinion from using these every weekend for shows. At heir brightest, they are easily brighter than the normal 200 W lightbulb, but they can be dimmed smoothly through the range up to that level. They are bright enough that it is wise to avoid looking at them directly. The white color setting appears to be the brightest, so they can be run comfortably at a higher setting when you use a darker color like blue or red. The color setting can also be adjusted to get any variation of color you are looking for. I use eight across the front of my stage, and that is more than enough to light the stage and spotlight performers.

Well, nothing scientific, but they are blindingly bright. I can not look at the leds withput it hurting my eyes. The actual brightness will vary depending on the voltage applied. I don't know of anyone who had done an actual measurement.

Nope, not even close. They put out what I would call "decorative light"...not enough to see by, just enough to look pretty. And the output varies a lot. Some are bright, some are dim. You get what you pay for and these were cheap.

Very, very bright. They are on the smaller size about 5x4 and about 4" deep. However they look clean and put out a flood pattern but the light up reflective signs from 100`s of yards away. So far no issues, brackets are a little flimsy but light housing is solid. I would biy again

Depends on the situation you are using the for. Just darkness...then yes they are bright
