Just goes to show you that it does no good to cast pearls before swine. After reading the excellent material and tests done by SupraSPL and the charts and graphs done by SDS, I noticed that the can of tuna that I was eating was round and my idea was formed. It is not so much of a reflector, as...

Overhead, true, but a business is not in business to break even, it is in business to make a profit. I think it is great that Realstyles is cutting out the middleman, getting his hands dirt, and is learning a great deal and sharing what he learns so that those of us who want to build our own can...

Great information, SupraSPL. I don't know how you find the time to help out us less technically savvy newbies and still run your own garden. You are a one man army and doing a great deal to power the transformation in lighting to LEDs. Have you considered setting up a consulting business where...

Six of those 990w COBs mounted on a good sized heat sink should crank out a nice amount of light.

So does higher thermal resistance mean that the cobs would run considerably hotter if attached to a plate between the actively cooled heat sinks rather than directly to the heat sinks? I thought that was the case, since everyone it seems does attach the COBs directly to the heat sinks, but I...

I see that my question above has already been answered in the Cbx series thread. https://www.rollitup.org/t/cbx-series-cobs-cumulative-info-and-comp.861717/#post-11345928

Good information. Thank you SupraSPL.

What do you think the best driver would be to run one of these?

Has anyone tried attaching multiple COBs to one side of an aluminum or copper plate and attaching a Alpine or Rosewill CPU coolers to the other side of the plate? I would use thermal paste between both the COB base and the CPU cooler. I would line up the CUP cooler so that it would be directly...

I just cut off the connection and spliced positive to positive and negative to negative. As I read in these forums, you can use just about any DC power source you have laying around to run the fan. I dug around and found some old cellphone chargers and a power block for an old cordless phone. I...

I am a newbie trying to understand how to build my own DIY LED COB light. I appreciate all the help I have found at this site, particularly from SupraSPL. The more I read the more I slowly start to understand the terminology. I would like to build a CREE CXA3070 or CXA3590 light at some point...

Hello all, I used to grow, both indoors and outdoors, back in the eighties and really enjoyed it. Luckily, I never had any trouble, but when our daughter was around four years old my wife asked that I stop growing and smoking for the sake of our child. I did so, but I always liked both smoking...

wrong forum, sorry

According to Google Map, the 40 acres that I inherited when by father died in May are 26 miles by road from the dispensary that has been approved for Globe. I am thinking about making a move.
