will this work(lighting related)

[az]

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!

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!

[BigDaddy]

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).
