I'm looking to upgrade the lighting in my 23L fluval edge, as I wanted to have a heavily planted tank.
I've done a fair bit of research on this, I've upgraded my bulb fixings for the larger ones to house bigger led bulbs, and I was hoping to add the popular mini fluorescent bulb in the gap between the hood and light arm.
The thing is, I've searched everywhere and I can't find a supplier in the UK that makes a bulb slim and small enough, that is daylight kelvin.
What are people doing here? Buying a US bulb and converter? Another type of bulb?
Another thought I had was to make an extension of the light arm using fibreglass and house another pair of MR16 bulbs. What are people's thoughts on this? Less effective than a small fluorescent?
You could order one from the States. You shouldn't need a transformer though, just an outlet adapter.
Personally I'm just doing DIY Cree LED stars which I'm mounting inside a straight length of aluminum channel which I'll be setting on the top glass.
