    I have a Dymax light unit with 2x 250w mh lamps and 2x 39w t5 lamps.

    Last night one of the mh lamps fused (I heard it pop). When I tried an old lamp as a replacement it also fused. Anyone know what could be causing this? Faulty ballast or starter? I checked the wiring and nothing looks wrong.

    Second problem. I want to replace the t5 lamps but the current ones seem to be non standard low output lamps at 39w when they should be 54w to fit the unit. To replace the lamps I would need to replace the ballasts as well but 54w ballasts will not fit into the unit. Anyone know if the 39w lamps (to fit 54w length) are available and if so where? I am in CT. Only other option I can think of is to fit the 54w ballasts remote to the light unit.

    Any advise would appreciated.

    Not sure what you're talking about here, 39w tubes are 3ft long and the 54w tubes are 4ft long?

    Dean - some of the Chinese imports has 39watt tubes at 1.18M and not the normal 93cm.

    You will have to go the the shops that sell the Chinese fittings or simply replace the ballast with a 54watt one - which is the better option btw.
