Need To Find A 549mm 14w T5 Bulb Somewhere In The 12000k Region

[Jules H-T]

I need a new 14W T5 bulb for my Symax Rex-2 system, but nowhere seems to carry them. I've found 20w+ bulbs of that size and colour, and 6000K bulbs of the right size and wattage, but I can't find the right combo.

Can anyone point me in the right direction please?

Well it's the right size. I suspect that "Warm white" is going to be in the sub 5000K temperature range though, and therefore much too low. I will check though, thanks for the response very helpful.

My next question (and, without wanting to sound rude, responses from people actually qualified to respond rather than thinking what sounds sensible to them only please because I can do that myself), is what is the consequence of using a 20W bulb in a 14W fitting?

ive seen a few people put a bigger ballast on a smaller bulb (eg a 40w ballast on a 20w bulb) it makes the bulbs brighter but in return the bulb dont last as long do ot the gas getting used up quicker.

based on that i cant see it being a problem as you would be underpower the bulb rather than over powering it. hjowever it might not start properly due to the lack of power.

wait untill you get another opion though.

disclaimer
its upto you and not my responsibility if it goes wrong

Depends on the ballast.... if its electronic, it may not light the tube at all ! But most aquarium lighting is still "magnetic" (read "cheap" !) and usage is really non critical, you should be fine running a slightly higher wattage tube.
The opposite (running a smaller tube) is a common bodge, and I have ran gear this way for YEARS.... the tubes will only take the current they require - and in my experience life is exactly the same.

However, I think I have found the exact tube...
