Cidly Apollo 10 worth converting to COB?

Ive got a like new apollo that isnt in use. Here are the factory specs...
APOLLO 10 LED GROW LIGHT
Lifespan: 50000Hours
Working Environment: 45%-95%RH, -20-40℃
Working Frequency: 50/60Hz
Input Voltage: AC100-240V
Output Voltage: DC32-45V
Power: 370W
Net Weight: 7.35KG
LED Qty: 150pcs*3W
Size: 609*283*85MM
PF: 0.9
Output Current: 700MA

It currently draws right about 300 at the wall according to kill-a-watt meter.

Its got 5 dual channel drivers that put out 34-50v @ 650mA.
I could remove the LED plates and replace them with COB's.

I have no idea what kind of efficiency a unit like this has from the factory, but Im guessing its pretty bad.

Is it worth upgrading a unit like this or better off just putting the money into a completely DIY light? I could probably get $200 for it on craigslist.

I COULD put in 20 cxb2530 with 2 in parallel on each channel of the drivers to reduce current to 325mA and get efficiency pretty high, around 53% Im guessing, for $200. Would cost more like $500 to go with single 3590's in each spot... and get 60% + effeciency.

10 3070 would come in a little cheaper and still kick out some good lighting with half the work of the 2530s

Yeah, I looked at those on cutter, they are nearly the same price as the 3590's tho. Im curious if anyone with experience can guestimate what kind of performance boost I could give this light by going to cobs over the 3 watt chips. I suppose it would be easy enough to just add a few cobs and leave the rest alone also.

How efficient are the 3w chips? You would need to start there. Another thing to keep in mind is that plants don't necessarily like being deprived of a majority of the light spectrum. Red and blues chips will work but adding all the rest of the colors (white leds) helps.
