Bulb came in a box with a sticker that says 1313BU-CV Par38 8W. Over that sticker they just placed another sticker that says 1313BU 15 Watt. The bulb itself has PAR38 8W written on it. I took a power meter and measure the power drawn by the bulb... 8 watts. By my best guess they took an 8 Watt bulb and are trying to pass it off as 15 Watt one.

This bulb is very bright! (500 Lumens) I've been using it for over a year with no problems. My Venus Fly Traps are growing like weeds! :0)

I was a little skeptical of these lights, but they have exceeded my expectations. They are very bright, and a great addition to any lighting setup for more oomph in the vegetation cycle. The only downside is that I wish it had a little more range in its wavelengths besides pure 450nm. My research tells me that plants would grow a little better when they get more of a subtle range of blue wavelengths. It has been working great though; my plants' leaves were starting to turn a little yellow from too much red light, since blue light helps the development of chlorophyll. Two days under these guys, and they are healthy and green again!

I may need more of these in the future and due to the good value and modularity of these, I may buy several more instead of a pricier, higher wattage single unit.

Honest reviews on LEDwholesalers 1313BU 8 Watt PAR38 Blue LED High Power Grow Light

A lot of reviews on this are bad because they thought they were getting a 15W bulb and it was an 8. Amazon seems to have fixed the title but didn't take down the reviews.

So, the bulb is 8W and works perfectly. I bought it for a nightlight for my aquarium actually, it's plenty bright and seems to be very well made. I would buy again.

This is the third time I order some form of bulb from Amazon which comes at half the claimed power (see photo). I don't understand why they're not doing anything about it.

Returned the bulb and got a replacement. The new one is still 8 Watts.

I decided to give it a try anyway starting some Russian heirloom seeds. They all stretched to no end and died.

This bulb is terrible.

Returning the second one too.
