Great value LED grow lightI mount 2 of these in a $1 cake pan with a 3"x3.8"x.125" aluminum bar and a $10, 95W CPU cooler on the outside to make a 100W grow light for less than $20. They work great in my indoor hydroponic garden. My plants love them. The only down side is the solderless connector. Don't try to put any wire bigger than 16 AWG into them. I prefer to pull the plastic cover off the connector and solder 14 AWG solid wire into the connectors and then cover the connector with RTV. That makes a solid, safe electrical connection. With the CPU cooler, my LEDs are barely warm to the touch.
100w full spectrumLights work great.
Quiet and made well enough to do the job.
They run pretty cool too.Direct voltage also has the best customer service.
Excellent add-on for my 90 watt CO2 LaserI recently purchased this as an add-on for my 90w CO2 laser. I didn't wanted to be able to adjust the current so that I could set the max current limitations as well as see the current output to the laser tube. This is critical to the overall lifespan of a laser tube and this unit was plug and play with my MJYG 100 power supply. Excellent buy!

very happy with thisBeen using this for about a month and a half now and it has been great for me. There web interface is so well thought out and makes my life so much easier. Little things, like having an indicator for when the z probe is triggered (and whether it's high or low) on the main screen, saved me so much time and trouble during the setup process. One thing I don't like is that there is only one option for bed leveling: mesh. You probe, say, 90 points on your bed to map the high and low points of the bed, then every time you print you just home the z axis. What if the bed becomes tilted between prints? A 3 point probe before printing that tilts the mesh would be better. Maybe add UBL.
I'm using this on my creality ender 4 (converted to CoreXY) and it works wonderfully. My printer is almost silent and I have 256x microstepping going too. I'm using the paneldue clone from this very site, which is also very good.
I was surprised to see the speed of uploading files via there duet web interface, I used a serial interface before (10 minutes to the duet's 2 seconds)
There's a Cura plugin that lets you print directly to your duet too, but I think Cura's latest update broke a lot of plugins. We have to wait for a plugin update or use an old version of Cura.
A few tips:If you plan on buying the paneldue, I'd recommend the 5" or larger, if you go smaller you get a lower resolution screen and I think the user interface is laid out differently because they couldn't fit everything.
Also about the paneldue: I wouldn't recommend trying to use the SD card slot in it. The duet always defaults to the micro SD card, so using the reader in the paneldue is a pain in the butt. Which leads to my next tip:
Buy a micro SD card. If you don't have one, buy one. The firmware goes on it, so the duet won't work without it.Gcode files can get pretty big, up into the hundreds of megabytes. If you don't want to be cleaning your micro SD card all the time, get a nice big one.
efficientI have two grows of identical plants and the one using full spectrum 50W LED looks way better than plants under 300K LED arrays. I plan on building more full spectrum LED arrays for their more efficient use of electricity..
handyI have several 12V solar systems on the property and these make great at-a- glance battery monitors. I may put a few more in cars and of course I have one just on gator clips for portable use.
