In a 4x2 space, would it be more efficient for 2 of these or 1 400-watt?

Two would do great since they grow and most of the light is then blocked from the sides to the other plants. Thos would create even cover

1 could take on that size space but 2 would give more intensity and prob would be better. Way better than HPS because even with 2 of these GL60 LED's, the temperature will so much cooler than a 400 watt hps

I think you will be OK. If you do the math, 6X200 = 1200 watts. That's easily handled by wattsup. Be careful to connect the solar cells to the "source" end, also I would use a diode to prevent any chance of backflow, just as a safety feature.

Absolutely! It never hurts to operate 2 at the same time. That's what I do and it takes care of our 2,000 sq.ft. Home. Consider the size of your house and g by that. These are the best you can buy in my opinion.

It's gonna be better to get two having one hooked up to 400 rms is overpowering the sub having two hooked up to 185 is not overpowering it but it isn't gonna under power it so 2 is the better option

Depends on use. Lights and Ceiling fans, 250w is fine. If you have a Electric ceiling heater That requires more watts, then the 600w I would use. Hope this helps.

400 would be pushing it. I have a 600w and it does fine. I would say the minimum would be 500w but it really depends on your total power consumption system wide.

Watts don't exactly matter. Quality over quantity. You'd be way better off having a kicker 500x1 mono amp than some cheap 2000 watt amp the cheap amps give cheap power and a quality amp will give quality sound

You will need two Amps then. 1 won't be hitting them that hard. 4 to 1 amp for a 1200 watt amp. If you get a bigger amp you will need to buy a compositor and much more and bigger wire.

I would go for a more powerfull option. In my opinion, one unit of this model, would be suitable for 13x13 ft. area.

The only issue you may run into is if you want to stay in peak efficiency, which is usually around 50% give or take. Also note that running multiple(3+ probably) hard drives adds up on the wattage used too.

Given that your use will be a bottle warmer I would suggest going to a 400 watt unit

no. it wouldn't really provide enough light for that large of an area. a 400w would probably work for your system. 3 of these bulbs would give you 375w.

Informal rule is twice the maximum load in Watts (for surges when certain equipment starts up). So 500W is all you'd need.

Depends on what else you're running but, I would recommend at a minimum a 550 watt unit; 650 would probably be better; 850 if you want to future proof your computer. This all assumes you're using a desktop and not a laptop computer.

I would go with at least the 50 watt. Probably the 100 would be better. You can always put it a little bit diagonally in the tank. it is ok to fully submerge even the top part. I would consider going with 2 50watt heaters with one on either end of the tank for a more even heating effect. Plus both heaters would last longer because neither one would have to work as hard.

A difference, yes, but getting 2 of them (or a larger model) would be better. My shop is 680 sq.ft. It will do most of it ok, but there is an area it won't reach.

Overkill if you use high 10 watts. 6 Watts may do. But do you have have about 2.6 inches of space between your ceiling and your soffits?
