overdriving with WH5 ballast? Grim???

sundevil_brian · 08/10/2006, 04:23 PM

this question is mostly for grim but if anyone else know you can go a head and chime in.
i was gona go with a 6x39w T5 set up but due to budget constraints i decided that i would bump it down to just 4 bulbs.
but i will be using 2 WH5 to power the bulbs so i can do a dusk/dawn effect.

I saw a post a wile back that you (grim) accidentaly overdrove a bulb using two wires from a wh7. do you think that the wh5 will do the same and do you have any par numbers or wattage drawn from the overdriven bulbs?

also what bulbs should i chose for the 4x39w set up. if i can, i will be overdriving the daylights only and not the actinic

these are the bulbs i have to chose from

ATI 39W - 12000K Aquablue Special T5 HO Fluorescent
Blue Plus T5 HO Fluorescen
Actinic Blue 03 T5 HO Fluorescent

General Electric 39W - 6500K Daylight T5 HO Fluorescent

Giesemann 39W- 6000K Midday Sun T5 HO Fluorescent
11000K Aquablue Plus T5 HO Fluorescent
Actinic Plus T5 HO Fluorescent
Pure Actinic 03 T5 HO Fluorescent

UV Lighting 39W- 10000K AquaSun T5 HO Fluorescent
12000K Actinic White (50/50) T5 HO Fluorescent
Super Actinic T5 HO Fluorescent

You need to make sure you are running good endcaps if you were to try this. If you double up on the red leads (use 2 instead of one per lamp) it will overdrive the lamps. The thing is it is a dangerous set up. If you have a arcing condition in the endcap it is going to meltdown and possibly catch fire. I personally don't think it is worth the risk. I would drop some coin on the better Ice Cap reflectors and stick with a standard ballast setup. I guess if you mounted the endcaps in steel so fire is not an issue that would be safer.
