Thread: Mighty Mini RGB+W Constant Current Floodlight.

I didn't get a chance to build these last year. I thought I would share this clip. This is with a constant current circut working at about 89.5 ma with no thermal runnawy. They stay nice and cool. I did this with my phone, so the video doesn't do it justice. You get the idea. You can also see when I use twinkle effect on rgb set to white color. Well better late than never.

Great Job, have you detailed the mods you had to make to the controller and the flood? If so can you point me to them, if not can you do so.


Again very well done....

I used a standard ren24lv set up for 24v power supply with a block resitor at the regulator. Seems to be working fine. Just a little hot. We'll see how it goes this year. I'll replace it with a switching regulator if I have to.

Here's the pdf for the constant current. It was alot of sodering, but worth it. If you have any questions. Feel free to ask. I used 14 ohms 1% resistor.
