Aqualight Pro Series 150 upgrade to 250

[Chin_Lee]

I just upgraded my middle 72" aqualight pro to 250W electronic ballast. During the modifications I noticed the following:

1) on the 72" fixture, there are two fans that are controlled only by the outside two lights. If the middle light turns on, the fan will not turn on. If either of the outside lights turn on, the respective closest fan will turn on.

2) each of the ballasts have three wired output. Red is hot from the ballast, black is hot from 120, and white is neutral.

3) the red and black goes into the ignitor for each light.

4) the fans are spliced in very close to the 5 bundle of cables. Fans are 120v AC so one wire is spliced into the black and one wire into the white for the two outside MH bulbs.

5) Replacing the middle light I don't have to deal with the fans.

if anybody is interested in a diagram to do their own mod, show your interest on this tread and judging from the interest will determine if I put time into an electrical diagram. otherwise, i won't bother.

I'm just selling my 150w version to get a used 250w version

No, you are not selling yours, those are sold already

Justusfish, I realize this is a old thread. I am upgrading my ballast on my 150W Aqualight right now. I went with the Galaxy selectable e ballast. I'm thinking now if I should upgrade the lamps as well (seeing that all I have to do now with the ballast is flip the switch from 150 to 250).

I know the end caps are larger with the 250W bulb, are the 250W bulbs and longer as well? Or can I just replace the 150W endcaps with 250W endcaps?

Another cool mod is to rip out the PCs and replace with T5s. I took mine out and replaced the stock 36" PCs with 4 48" 54W T5's worked really nice and more options with coloration. I just sold them to a buddy after replacing with LEDs

If you wished to add another fan to the fixture, could you just splice it's wires to the same locations as the original fan(s)?
