    Hey guys got some stock of these inexpensive lights today and i was thinking of using it for my nano instead of the 150w 20000k.

    Sure i know somebody will say that the actual light emitted is not blue and is actually normal PAR 38 6500k filtered by the blue lens,but my logic is that even so only blue light reaches the corals and tank.

    Anybody see any potential problems with this?
    Has anybody tried this?

    Hi Falcon - it all depends what you have in your nano - what life stock that you WANT to keep. Yes - they will work fine, except if you have SPS corals that require a HUGE amount of light.... then, I would say, "no".....

    Jacques i do also have 26w of 10000k energy savers on the nano,and at this depth(less than 40cm) 80w is alot as its quite close to the corals.....you seen anyone using this?

    Oh btw it will be a sps nano...

    No - I have not seen anyone myself, using these globes. BUT - there's NO reason why it should not work!

    OK tried it and it was a huge flop,very little dark blue light is emmited for a 80w and does not spread nicely either.

    basically its like shinning a torch into your tank.

    Everyone be warned dont even bother thinking about these globes in marine tanks unless you want to use a a standard clear 120w PAR 38 globe for your cheato/macro/sump/scrubber.

    i'm sticking to my 150w MH and 2 X ENERGY SAVERS for my nano!
