So i was checking out a thread when i stumbled upon Odno (overdriven normal output) a method of powering a single bulb with a multiple bulb ballast.
Ok, here's the ticket, then... Overdriven Normal Output Flourescent lighting (ODNO). Most bulbs get their super long life (20,000 hours+) by running much cooler, at lower current levels than they are capable of. This is great for office lighting or other industrial applications where energy efficiency and bulb life are the most important factors. But we want to cram as much light over our small tanks as possible.
An overdriven F32T8 bulb will produce about 6500 lumens. Why the smaller 1" diameter T8 bulbs? They're more efficient and produce more lumens/watt. Two of these ODNO T8 bulbs will make more light than four 1 1/4" T12 bulbs in the aforementioned shop lights.
How does it work? Well a normal lighting ballast is responsible for providing power to the bulb. Most of these ballasts are capable of providing power to more than one bulb. Instead of hooking up multiple bulbs to the one ballast we can hook up just one bulb with all of the outputs together. So say we had a ballast that is capable of driving 4 seperate F32T8s. If we put all of that power into 1 F32T8 that bulb would in theory produce 4x more power. Below are 2 diagrams explaining the proper way to wire the ballasts to the bulb/s.
Although not necessary, it is recommended to install a fan in your hood. Overdriven bulbs get noticeably hotter than a normal one, although not as hot as a normal 55w Power Compact.
My question is to all you out there, has anyone tried this or do u use this method of lighting in your setup?
I just barely finished rewiring a 2 t32t8 ballast to one bulb myself and it seems somewhat brighter but i would like to hear any success stories from real world application.

<thats what i have to say about overdrivin
