Pentair Intellibrite vs Hayward Colorlogic

[kelemvor]

Don't be lulled into a false sense of confidence by the voltage. My light is 12v and has two 100w bulbs. 1a of current will kill, and 200w/12v=16.6a WAY more than sufficient to kill, and for the circuit to work you're going to need a 20a breaker...

If it were 120v, it would be 200w/120v=1.6a. You could put a 2a fuse or breaker on that circuit and have a much higher degree of safety; although still plenty of deadly current capability.

At 120v though, it would be much easier for current to travel where it's not desired... and salt water only improves the water's conductivity...

In either situation, you've got to rely on proper grounding and GFCI protection in case of a fault.

The pentair 5g appears to consume 50w (or 70w in the white only model?) which would still draw about 4a@12v but only 0.4a at 120v (which would be unlikely to kill)... hence me thinking 120v would be nice with the new light.
