If you only have a sawzall or hack saw, WD 40 can help with cutting the aluminum but a bar of soap is even better. Just run the blade on the soap every so often then keep cutting. Use a fine toothed metal blade as well, and wear gloves aluminum is very messy when it gets cut

I've replaced most of my lights with Quantum Boards from HLG. I cut my power consumption in 1/2 and increased my harvest. I still have one COB light but I'll be replacing that soon also. QBs give me more headroom over cobs.

Good point!!! I don't really know cause I've never used cob lights before... Strips either for that matter... Guess it comes down to what you see the plants liking... Really doesn't matter what WE like... Feel me???

I like to let others do the trial and error and I’ll come in behind them and buy what works best for the money. 400w hps/my would be my new veg and if I go led that’ll be for flower. I’m in no rush, just trying to research and figure out what is best.

I have quantum boards and they work great. However, if I was to redo my lights. I would go with strips for the more even light distribution across the canopy.

I am getting pretty even coverage. I can even lean into my canopy.. I love spanning a 4 foot space with triple lights. I bet I could even push it to 5 feet wide.

I'm talking about the 4 ft Samsung F-series (lm561c) or Q-series (301b) strips. They do come on a board, but the board is 44" x 3/4" (1120mm x 18mm), so they call them strips. You can get 1 and 2 footers also, but it is a little more expensive for the same coverage as the 4 footers.
If you're interested in strips, the following article explains them, along with some sample builds:

DIY LED strip builds have become very popular recently. The mid-power section of our forum is full of threads created by DIYers looking to build their own custom lights, and new builds and ideas are surfacing every day. If you don’t live somewhere where you have easy access to premade lights...

I'm a big fan of the Quantum boards. I have two 260w kits in a 5x5 with a 400w magnetic induction PAR lamp. I plan on buying two more 260w kits and putting one at each corner of the tent and replacing the induction lamp with a QB18 Emerson effect 4' strip across the middle.
Before that I had two 260w kits in a 2x4 dimmed way down. Super efficient and amazing coverage plus the power to run CO2.
I noticed some other companies are coming out with LM301H V3 boards but HLG doesn't seem to have anything yet? Kind of lame. I might order one from Neimi instead.

Really? You haven't seen my build then I guess. Haha
My brand new DIY Fixture.
Hey everybody. I've been working on this light for the past 3 days and was able to utilize that light that I won a year or two ago and spread the red, blue and white Monos more effectively. Reusing the drivers was the only thing that really sucked. I wish I could have just bought new meanwell...

Cobs work well, QBs however, are more efficient and they weight much less even with a heatsink. Add to that, they save 4 inches of headroom in a tent, and that can matter depending whit you grow. That said, my COB light has given me excellent results. Going to give the COB light to a friend soon, I've still got a few QBs sitting around lol! Going to build a light soon and going to add 2 more QB 304 to my first QB based light.

Run more QBs at lower power! Below 70 watts, you don't even need heatsinks! I'm eventually building a 9 board light for SCROG run at 50 watts per board.
