Hi all.

I'll add to this over time but thought I'd stick a thread up to stop cluttering Beau's journal Smile

Happy to answer any questions you may have.

I've built a few lights in the past both for myself and others. Only used COB led's so far but plan on putting one together similar to the quantum boards you can get as well.

This man taught me everything I know about led lighting. I have a background in mechanical and electrical engineering so had a basic understanding but not how it relates to grow lights.

I'd recommend watching all 6 of his basic guides and if you are a tech nerd like myself you'll probably watch all his others.

He started out just doing DIY lights and is now working for a large American firm building some amazing lights.

Is a treasure chest of data and guides. 

 

I'll add to this thread as I get a chance and I find interesting stuff

I put this 9 x cxb3590 light together in Sep 21.

 

Has a Meanwell HLG-600H-36B powering it and has a variable resistor controlling wattage.

At 160W at the wall I am getting just a little bit of bleaching on the odd leaf tip.

May need to reposition the overhead RAM fan to see if I can get a bit more height.

Almost certain if I use a smaller space I might be limited to about 70-125W at the wall.

They do seem quite efficient these cxb3590's.

 

9cxb3590

 

Beware of cheap Chinese variable resistors.

I had one fail within 24hrs and it meant the light was drawing 601W at the wall.

I got home just in time....

There most certainly would have been a fire.

Working on a temperature monitor that shuts the power off and simply uses a cfl to keep photoperiod in the event of another failure.

@macky 

Someone was looking over Me that evening I believe.

 

Hopefully the monitor I build will also detect power failure and turn on a 12VDC fan to keep the smell down.

 

Had a few power cuts lately. This could become an issue for Us all this Summer and beyond as oil/gas supplies potentially get squeezed.

I costed up the 9 cxb3590 light and its worked out at £580

I'm happy enough with that as the bud I have had off the 2 previous grows combined with £? for this latest grow means its paying for itself and for hopefully years to come.

Its drawing 160W at the wall and I can either raise the watts until I get to around 800-950 ppfd or lower the light.

I'm so glad I spent the extra using more crees as I feel its going to save a large amount now the utility company is stiffing Us all come April Fools day.
