That's a pretty rational approach.Good deal. I know I'm a worrier, I just want to make sure I have all bases covered. Thanks for the input guys!

I concur. Drilling the holes typically takes longer than tapping, unless of course you have a decent drill press.don't be intimidated by tapping holes, its not that bad. Ive broken my share of bits, but take your time with it and use oil. should be fine
The driver efficiency should be slightly higher on 240V and will be technically safer since you would be drawing less current (when I am on 120V I push 10-11 amps and you can feel the warmth in the wires/connnections). There are downsides to 240V though, the misc equpiment is more expensive, timers, DPST switches, GFCI, outlets, plugs etc and it can cause compatibility issues with extraction fans/circ fans etc. My watt meter does not work on 240V which is a bummer too because I like to keep an close eye on that to track gpw. Now I will have to use an ammeter.Running the meanwell htg-120-1050..
Differences between input of 110VAC and 220VAC?
Aside from amperage draw. I plan on installing a dedicated breaker for the room so that's not a problem.
Everything else running will be 110VAC so having to run two separate lines will be a pain.
EDIT:
Ok so I just went over the spec sheet again...
Actually looks like the power factor is better with the 110VAC.
But I'm reading 50A inrush current?!?
Holy shit. So I'm going to need a big breaker for these bad boys??
Can anyone confirm this?
Also,
What are ya'll using for timers and on/off control?

You can find drill presses on craigslist for cheap.I concur. Drilling the holes typically takes longer than tapping, unless of course you have a decent drill press.
If you're considering a 240v run and use 4 conductor wire you should make a plug in subpanel. This would allow you to safely use 120v as well without any questionable wiring. It's not really kosher to split 240v circuits without a sub panel according to the NEC. At least from my understanding.[...]
If you were to run 12/3 or 14/3 romex style cable you could use 2 of the conductors to carry 120V legs and the third conductor to carry a neutral, and the ground makes 4 despite being called 14/3. To make matters more confusing, non romex style cable is sold as 14/3 but only contains 2 conductors + 1 ground. So 14/3 romex style would allow you to have both 120V and 240V on the same board using only one wire.

Thought about using sheet metal screws and eventually decided to instead use fine thread screws. I'm so glad I did this, because I can effectively remove a COB and transplant it if I need to (which I've done). If I would have used sheet metal screws, chances are that something would have went awry during this process.If I just drill pilot holes the sheet metal screws will effectively tap themselves.
What's the advantage of tapping a fine thread I into the sinks?
LOL!OR....break the tap in the hole. Sounds like sqweesnaaaap. Woops.
Hold down force on the cob cannot exceed 75 ft pounds on the screws. It's in the spec for both holder and COB.If I just drill pilot holes the sheet metal screws will effectively tap themselves.
