Cold Cathode Moon Light

[smithrc]

Got my cathodes this morning, using the transformer off a rechargable drill atm but a universal adaptor is on the way, well chuffed, this is at 12v with blue cathodes, uv dont seen to illuminate the tank at all.

make sure the fish still sleep - we've dropped the voltage to 6V so the light is dimmer as we kept our fish awake for 2 days.

i only set it up because i couldnt wait, i turned it off so they could get some sleep

Have just ordered my Cold Cathode tubes from Ebuyer

Will fit them asap, and post up some pics !!

Actually ordered 3 sets, and 2 sets of the triple-LED lights to 1 set of tubes for the tank, and the other lights will possibly be used in my car !!

Thanks for the guide on the moon lights its great. I was just wandering about the regulated AC/DC power supply. I have managed to fine a un-regilated power supply at my local DIY store and I was wandering if this would be OK to use?

Thanks.

 

[smithrc]

un regulated will be fine.

this mite seem like a dumb questions but are the cold cathode tubes water proof or will they need covering?

well i havent personally dipped mine into the tank to see, but it appears pretty water-safe

a bit of insultating tape around worry-areas is always good too!

the ones i bought are sealed in plastic

lol - i like to open plan PC look!

I hope you are getting an adjustable voltage supply as 12V is too bright.

We run 2 12" tubes over our 120l tank at 6V and its fine.

Have finally got round to fitting my 2 x 12" Cold Cathode's to my 4'6" tank

Have used an old Nokia mobile phone charger as the power supply (10v), will see how that goes for now, if the fish don't sleep, then I'll have to source a lower voltage supply.

Here are a couple of pics of them in place and on. But being daytime at the mo, I can't get a good shot of them illuminating the tank (will do that tonight!)

Got the Cold Cathodes from Ebuyer for about £4 !!! and the power supply was FREE

Also painted the inside of the hood, in Silk White emulsion, to try and give that bit more reflection down into the tank
