i have a WH5 ballast with 2x50watt, my canopy is big enough for 2footers which means i can go 4x25watts, que is can i put 2 25watts in series and hook it to 1 50watt so 2x25(seires) + 2x25(series) will it work? thanks for any help in advance!
Yes.. you can drive two bulbs in series with an electronic ballast
I.e. 2 2 foot bulbs could be driven by a ballast designed to run a single 4 foot tube.
thanks BD, an expert opinion is all i needed, time to go bulb shopping!
Note that you can NOT generally do this with a non-electronic ballast (tar). I've tried :)
Just for future.
You may go to the Fulham site and get your wiring diagram. Just provide lamp type (T5 Linear HO) and wattage (4xF24 HO):

So, in your case you can use WH5 (see attachement)

i doubt that would work, my wh5 has 2 outs of 50-55watts, lamps are 20-25watts each! this is what i am planning!

Here's your diagram

this is in parallel, which means if 1 bulb go out, the other bulb its sharing the power with will go bad, where in series if 1 goes bad, the other will shut off!
not sure if that makes any sence or not!
Well, that's how Fulham says you should wire 4 T8 F25 to a Workhorse 5.

This is strange. I have WH5 and it has 5 wires: 1GRN and 4 "Signal"
Now, if you will wire as you draw, than you will have 2 lamps in series and if any of them will be broken the other one will go off-line.
In Fulham drawing all of them are in parrallel, so if any of the lamps shutted down/broken the others will still be operative. I tried :)

The "usual" setup is to run the bulbs in series (i.e. 2 2 foot tubes in series to imitate a 4 foot tube). Fulham is obviously able to deliver power to the bulbs in parallel (better, as a single burnt out tube doesn't affect the others).
