Spider plant loves the light 8/23/2022
I run these at about half the rated wattage so heat sink size wont be as critical and my spider plant and other plants are thriving. The LED is warm to the touch and should last much longer.
 
Interesting device 9/9/2021
I did some experimentation on this device using a variety of voltages, currents limited either by my power supply or by a low-ohm resistor, and heat sinking. I was able to achieve a nice brightness with modest heat sinking -- by using a very thin layer of JB Weld to affix the device to heatsinks. I have three of them on top of one of my aquariums and while they dont seem to work well with my water plants, when I forget to turn them off at night, if I wake up at 4 AM I think its sunrise! Ill use more of them for my Halloween display.

Needs a bigger heatsink... 7/7/2021
Remember that line from the movie Jaws --- I think we need a bigger boat? So these are ridiculously bright at 12VDC, and my quickie test withOUT a heatsink showed that they draw about 3 amps each from a non-current-limited supply. In about 3 seconds, the test unit got way too hot to touch, and Im not sure why anybody would disregard the heatsink suggestion. Im just remarking that if it has 10 watts of light output, itll have nearly 30 watts of thermal output too. A dinky TO-3 PCB style heatsink will probably be inadequate. But with the right heatsink, these are jam-up good! If I still kept lizards, Id use a couple of these as lizard heat lamps, as theyre brighter than the $30 fluorescent bulbs I used to use, and warmer than the $25 heat rocks I used to use, which were merely big resistors molded into pink-colored plaster. Ill experiment and may post my findings later.

MUST HEATSINK TO A REAL HEATSINK MATERIAL 5/29/2021
THE USERS MISTAKES WERE CORRECTED BY MPJA STAFF... I HOPE HE WILL BUY A REAL HEATSINK HERE AND FIND THOSE LEDS WORK LIKE OIL... RICHARD.. ENGINEER

MPJA Response - Changing my rating from 5 to 1 4/11/2019
Yes a 4 bulb florescent fixture has a large surface area but it is very thin and the heat cannot transfer fast enough to keep the LED cool. That is why heat sinks are compact with fins to have a large surface area very close to the LED. Plus Steel is not the best conductor of heat it is about 1/6 as good as aluminum.

Changing my rating from 5 to 1 4/4/2019
I used 3 of these 10 watt LEDs in series with Stock No 31539 PS LED Driver, 30W DC Output, 110-260VAC Input. They were mounted on old 4 bulb florescent fixtures. The fixtures provided huge areas for heat sinking and used gobs of sink grease. I made three of these fixtures. This setup worked for two weeks and then one LED failed. I had an extra LED and replaced it. Another LED has failed on one of the other fixtures. That is 2 out of 10 LEDs within two weeks. Not good. I cant take chances on my germinating tomatoes and peppers so I have placed the florescent bulbs back in the fixtures. Very unhappy at this point. I wont be buying any more of these 10 watters.
 
Very Good Modules For DIY LED Grow Lights 2/20/2019
Very inexpensive modules at the consumer level, while the specs state they need a pad, a dab of thermal grease, which MPJA sell works just fine. Nine LEDs per module and a very good spectrum. But even better is buy a 9 volt power supply such as this https://www.mpja.com/9-Volt-Power-Supply-167A-Switching-Meanwell/productinfo/18367+PS/and you are good to go for a very small price for the light output they provide.

Fantastic so far! 2/14/2019
I mounted 3 of these on the center cover of my flourescent light fixtures. Now I have 4 48 inch flouro tubes and 3 of these LED lights in each fixture. The LEDs are VERY bright and must have good sinking. Use a lot of thermal grease to conduct the heat and get the LEDs flat against the metal used as a sink. I use 3 LEDs with the 30 watt power supply 31539 from MPJA. I have one fixture running for over a month now. I am so happy with this result and I cant wait to start the new seedlings in a month.

Really helps plant growth 1/11/2019
I couldnt believe how fast my plants started growing after this. Definitely recommended.
