Okay, Being that I got some cheap LED COBs, I am going to try to put something together. I was inspired by someone who used a muffin pan (sorry, can’t remember who is was togive credit) so I decided to go that route. Instead of using a regular muffin pan, I decided to go with a “Muffin Top” pan as it would allow me more room and have less “cup” to contain heat.
Here’s what I have:
This is the pan. I decided to put the COBs inside the cups as they are not very deep and the bottom would allow for better attachment of cooling fans/heatsinks. I will probably use 120MM fans but may incorporate this 300mm x 140mm x 20mm heatsink as well. Tghinking about cutting in half, lengthwise, and run over three cups. The COB’s are 50W AC “driverless” that I got from a buddy of mine. He got them to repair a bunch of Security Lights and had these left over. I think I paid about $0.50 a piece. I have both 6000K and 3500K and my plan is to incorporate 4-3500K and 2-6000K into this light (question to follow) Though I haven’t gotten a box yet, I will also incorporate this digital meter which reads out Voltage, Current, Power and Energy. Also incorporated in the “Box” will be this Adjustable Voltage Regulator. And, of course, these will all be tied together with thes magnificent Wago connectors.The plan is to have 6 COBs, 4-3500K and 2-6000K. This in mind, I have a question to the “Peanut Gallery”. Should I place the 6000K COBs on opposite ends, i.e.
6000K - 3500K - 3500K
3600K - 3500K - 6000K
or would it be better having both inthe middle, i.e.
3500K - 6000K - 3500K
3500K - 6000K - 3500K
