what is the rated output in lumens?

I too would like to know the light output in Lumens. I have seen other "Replacement for 500W shop/floodlights" that only draw 7.5 Watts, (1/6 as much power to run them as this one), and they claim the output is 1820 Lumens. I suspect that is less light than what this unit puts out, but for the sake of comparison, please publish the light output in the light bulb industry-standard unit of measure, (Lumens). Thank you.

The one I received is not as bright as a 500 watt halogen fixture, although it is still very bright. The manufacturer claims 4500 lumens.

I don't know the exact lumens, but it seems to be equivalent to a 40 watt bulb however, the is very directional and would probably work for your application.

Lumens: 1715 Kelvin: 6500 Voltage: 120 Wattage: 27 Average rated hours: 10000 You can also use the Watt to Lumens calculator. Lumens/Watt value for florescent is about 60 to 65.

This unit is rated @ 120Vac, 60Hz, and a Max 6.5 Watts. NOTE: This unit produces 300 Lumens. You can't convert directly between Lumens and Watts. They are measuring completely different things. Lumens measure the flux of a light being produced by a light source or received by a surface. Watts measure the amount of power used (P=EI).

I'm not sure about the lumen output rating, but our backyard is over 200 feet deep and 80 feet wide and this light fixture is brighter than any other light we've had!!

Typical 1W LED gives 60 lumens. Most advance 1W LED can give 95 lumens. You should aim into around 70W LED for your satisfy equivalent.

I don't know what the exact lumen output is, but our basil plant did really well under its light at about 6 to 8 inches away while the glow panel was new. Unfortunately, the life time of this device is not good. The LEDs, especially the blue ones go dim or die outright in less than a year at a usage of about 10 hours a day. After enough LEDs fail, the whole rest of the array no longer lights up at all. I would rate this grow lamp much higher, if the LEDs were individually user replaceable and purchasable at a reasonable price each.

The light output depends on the specific F15T8 fluorescent tube used. These are generally 15 watts, initially producing around 700-900 lumens, depending on manufacturer.

I don't know what lumens are, but it gives outnext to nothing in light. If you expect to see by this light, don't buy it.

It is not super bright. I would guess on the lower end of the lumen rating per watts. I bought them because the light is on all the time.

It has 11 lumens of output, and this is a great flashlight. It is used often by mechanics and it takes a beating. I have had mine for 8 years and it still works great.

I don't recall seeing a lumens rating but this is my third led light and it's one of the brightest I have bought so far and love it.

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

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

The rating is 250 lumens at 12v. The LED is compatible with 25v, same 250 lumen rating. These LED's are awesome for the price!

74 Lumen Output (Estimated Max Lumen output only. Actual performance depends on operation conditions, cells used and flashlight.)

I've read somewhere they output 1200 Lumens with power at 22 W. More or less it compares with a 75W incandescent according to some charts. This doesn't take efficiency into account. I'd say a bit more than 75 after having had those for about a year. HTH.
