The top driver picture may run 2. It all depends on the drivers actual output. I don’t have much faith in these products or their real output based on labeling.


The second picture is a fan driver.

Yea, I knew the second was the fan driver.

Would I be able to see the actual output with a multimeter? There are four of the led drivers, so I may just stick to one 1812 per driver. That should work out to 120 watts of cob, if I have my math correct?

Ok boys and girls, I finished one of my PlatinumLED conversions tonight and thought I would share the end result.

It had four drivers 55-100v / 550-600ma. I pulled two of them out and ran 4 COBs in series is two sets so I can turn each pair off and on individually with the bloom and veg switches. So far been running an hour with no heat build up except a warm spot on the glass panel in front of each cob. All COBs on running at 144w at the wall including the fans. I calculated 12 w for the fans which leaves us 132/4 = 33 cob watts each.

Nice. Did it take very long to convert?

Well I have done a smaller panel last week, so knew what I was in for. I also took some time after opening the PlatinumLED and decided just how I was going to do it before I took it apart. With the help of @BigSm0 i decided to pull out two of the drivers and run the four COBs in two sets of series off the two remaining drivers. So I now I have a spare set of drivers in case something goes wrong down the road or a future project.

And I still have not answered your question?

It took longer to clean the 3 years worth of dust out of it. I spent about two hours talking it completely apart and cleaning everything that was going back inside the case. Then because of the forethought it only took an hour of uninterrupted work to put it back together with the COBs. So three hours of uninterrupted work if you clean it up good. I’m sure some electrician types could have done it in 15 minutes, I’m not one so took my time. In case you were wondering there was no soldering involved.

Something else that saves a shit ton of work was that the LEDs were all on a separate piece of metal and screwed onto the heatsink. So they all came off just by removing a bunch of screws. No cutters required to remove them. On my other panel this was a nightmare to get them all off.

P.S. I have another one to convert. I could start a thread just for it with lots of pics if you need. The PlatinumLED is pretty solidly built and this made it easier I’m sure.

I’m very happy that worked out. I wasn’t sure the drivers had it in them to push the 2 cobs per driver. This is a big step in led conversions. 2 spare drivers never hurt either.

Yea and this light is nice enough that I wouldn’t mind, down the road, replacing the drivers with a decent one. This would allow me to drive the COBs at their full power. I am redoing this one to have the middle two COBs come on with one switch and the outer two on the other.

That’s a great idea! Did you leave the glass? I would consider removing it. It does decrease the amount of light and will trap in heat. 50% of the heat is in the back and 50% from the front. You would be running much cooler with it removed.

Good to know, when I pull it apart to rewire it I will pull the glass out.

Nice job looks good and tidy

Hey @BigSm0 the time has come, my lights are off for the summer, the cobs are coming!! I've had a look at their insides and too a few snaps. You were right about how they use different components. 2 viparspectras with different brand drivers lol.
Anyway could you or any one point me in the right direction to convert these.....a 450 + 600. Am i right in thinking i would divide the voltage of the drivers by the voltage of the cobs i choose to deterain how many each driver can take?

the 600^^^

the 450^^^

Thanks in advance guys
