Lighting DIY mars conversion. Questions and answers here.

I might try removing the diodes on an old mars ref 48 that's been restricted to bloom only since I destroyed the switch innan attempted hack. Anyone keen to help with that if i take some good reference pics?

Always.

Right on brother! here are the only original shots I can find it was butchered thereafter.

What it looks like as of now... Smh.

Trying to rewire with the original reference has given me hints but not the full picture, I'm stuck at this point here wandering wtf.
Are they earthing?

Hi! I wish I had found this forum and thread before I bought everything and got started on this grow. This truly seems like a service to the community.

I have 6 of the lights pictured, so I've got 6 12v supplies that they use for the fans, and 36 of the LED drivers shown total.

I'm a bit into it now with a couple of Mephisto autos (one tent is doing well enough, the other doesn't look as hot), and several of my panels are failing, but I tested all the drivers, and they all still work - Based on everything I've read here, I want to upgrade the lights pictured to use COBs.

These lights don't have any actual heatsinks, just the flat aluminum panel to which the existing diodes are soldered.

I'm using 2 2x4x6 tents that are very snug in some closets, so the less heat, the better.

How much light do I need for each 2x4 tent, and what's my best initial cost option? I was looking at the Citizen 1212 and 1812 I feel like I'll upgrade eventually, but I'm after the best bang for my buck right now. Also hoping to get away with stripping the aluminum panel and using it for a heatsink.

Any thoughts?

Thanks!

I'm not sure exactly but 100w per square foot sounds about right. Depending on your location the Citizen 1212/1812 would likely be your best bet as they are extremely cost efficient whilst being a top shelf product. I myself have converted to Vero SE's as they come with a very user friendly poke in solder less connection and are far more available to me, but whatever suits. Citi 1212s pull 35-36 v, @BigSm0 Are they available in larger fv? So 0.700a x 35 = 24.5w per cob, if you can double the cobs fv the watts out will double up to the sweet spot of 50w. If not 36 x 24.5w = 882w/divided by 6= 147w from each light.... hmmm im not sure about how economical this is all sounding to a pro but im just getting the ball rolling.

I think it would be a better idea to increase the output of the cobs upto 50 or 100w to save in material cost and output, im just not 100% sure im being factual so well wait for the boss to rock up!

I'm in the states, I have access to most any COB I've been able to find on the internet so far.


100w per sq foot? That's about double what I was planning for. I was going to shoot for 300-400w in each 2x4 tent. Is this too little?

 

[2MinutesHate]

Will there be any difference in the wattage in these lights if I were to wire 2 36v in series to 1 driver?

 

[2MinutesHate]

Disregard, that'll just make more use of the driver, rather than changing the properties of the light. The only 72v COBs I'm finding are cost prohibitive.

 

[2MinutesHate]

Maybe I should look at the 1825 instead for its additional voltage? If I understand everything properly, those should work out to like 36-38W? The 72v Cree are just more money than I'm able to spend to outfit both closets at this point.

For a 2x4 tent I’d go with 100-150watts. With 1212’s you will get 25 watts per cob and 1812’s you will get 35 watts per cob. Is there just one panel in the tent?
