    hi All

    Can anyone tell me if this light will be safe to use on a reef tank to bring out the flourescent colours of coral - UV Blacklight?[​IMG]

    I recon the light spectrum is not suited, rather go actinic

    I used those, except blue, as my first moon lights. as sealed and waterproof as they might seem, the salt got hold of them in a month. the spectrum of blue was also not to lekker.

    thanks Guys. I'm still quite green at the reef scene and it is amazing how in depth the subject of lighting is. I've still got alot more reading to do but already have a better understanding. Thanks for the link Lycan. its a pity that the guys from the LFS don't explain it like this.

    Agree with the previous message - get an actinic, but make sure, if you are after the fluorescence, that you get a true actinic where the peak is only in the 420nm area and not in the blue (450nm and onwards) as this will wash out the fluorescence you are after. An alternative could be to source some of the new LED's but again you need to find the ones that contain 410/420 nm LED's as well as other blue, which might prove difficult at the moment in SA, but are avialbel from the UK. Hope this helps.

    UV also causes photo-inhibition in plants - and i would expect the same in corals. so not a good idea at all.

    Bad idea, i remember reading somewhere that the ultra violet rays kill some important bacteria thats needed in your display tank.
