I looked at the brand of the bulb and they are 20 watt Plen Plax
When looking at http://www.ahsupply.com, I notice the bulb lengths are not
in the standard 24", 36", etc. I take it 21.1" = 24"? And 34.1" = 36"?
Kind of confusing. My bulbs were sold as 24". So I am assuming I cannot
use these bulbs in my standard ballast? I guess I need to buy their "bright
light kit" to use them, but apparently you have to install said kit onto a
pre-existing hood/ballast (they don't come in one). Hmm... The plot
Looks like I am getting myself into all new territory in regards to
lighting. I was assuming it would be as easy as finding the correct bulbs
for my pre-existing hood. Is that still an option? Higher powered bulbs
for a standard aquarium hood? Or do I have to start completely from
scratch? My hood's not in the best condition, but it WORKS, and I was just
hoping to not have to get into another $150+ adventure (like I just did w/my
Any advice on this lighting madness would be greatly appreciated!
