Lighting Assistance
hello, i'm the new guppy in this pond and i need some help with a lighting problem:
i run a 331mm (13") 10W T8 flourescent tube and it has burnt out the pcb after about a year. it blew the fuse once before but i replaced it with the correct replacement so it wasn't that that caused the meltdown. i would rather not try to find a new pcb if i can help it ; I would prefer to run the tube from an external power supply to stop this happening again. the problem is, i thought all flourescent tubes needed a starter and i can't find the one in my tank. the suppplier (aa-aquarium.com) is no help at all. can anyone advise me how to rectify my problem? thanks in advance, Parasite Last edited by parasite; 06-03-2008 at 08:57 AM..

Welcome to AA!
What brand light fixture is this with a transistor in it? I believe a T8 bulb is just a normal output fluorescent bulb. Anyway, not all bulbs need a starter. RS (rapid start) bulbs do not need a starter to fire. I wired my VHO's and reg. fluorescent bulbs. 2 wires on the ballast get plugged into the wall and 6 wires go to the 2 bulbs (wiring may vary depending on bulbs and ballasts). There is no transistor involved. |

cccapt,
thanks for your rapid response. there is s a code on the board ; KE10W-12V-1. the board has the following items on it: 2 x 2way screw connectors 4 x diodes (i assume the bridge rectifier) 2 x large brown resistors 2 x small wire wound resistors 2 x transisor things (although they may be voltage regulators but too much damage done to read) 1 x transformer 1 x large black thing (possibly a coil). i am guessing that this is some kiind of smothing circuit for the ac / dc conversion. if you know of a rapid start set-up that i can use to replace this junk, please advise me. thanks again, parasite. |
