    Hi Guys

    Like many fellow reefers i have been exploring the use of LED lights. i have found a local supplier who is marketing an aquarium LED strip light. here are some specs...

    White - 14000 Kelvin
    280 Lumens/meter
    4.8 watts/meter

    Blue - 20000 Kelvin
    170 Lumens/meter
    4.2 watts/meter

    Will this work for reef tanks with corals?
    How does one calculate how many to use?

    My DT is 1200 x 600 x 600 with softies and LPS.

    any advice will be appreciated.

    @Slims, based on the specs you are quoting, I would say those would only be ok for supplemental lighting for color, or shimmer.

    280 lumens p/m is not a lot, look at the specs of the chips in the higher end LED units and and you looking at around 300LM pre LED CHIP.

    And for a 1.2m x 600 x 600 length your are going to need a min of 48 of these chips.

    My calculations are extremely rough, but this is just to give you and idea that IMO this wont work alone.

    Hope this helps.

    Just remember that those lumens are measured directly under the LED! On most leds bar your high end radions and PS the lumens decrease exponentially as you move away from that main beam when compared to a halide!

    To follow up on RA radions and ps units are running 145-150 watts of led to cover a area of 600mm x 600mm and pushing it at 600mm deep!

    100 percent agree with RA they are supplemental lighting!

    That does help. When you say "48 of these chips " are you referring to the high end LEDs
    ?

    I suppose the lumens will decrease even more having to penetrate water?

    YES, unfortunately:

    Here is an example of a Radion LED covering 60x60cm

    8x Cree XP-G Cool White LEDs run at 5w each
    8x Cree XP-E Blue LEDs run at 3w each
    10x Cree XP-E Royal Blue LEDs run at 3w each
    4x Cree XP-E Green LEDs run at 3w each
    4x Osram Oslon SSL Hyper Red LEDs run at 3w each

    Here is and example of the PHAROS also covering 60x60cm:

    Cree XPE Blue 3 Watts x 4
    Cree XPE Royal Blue 3 Watts x 12
    Cree XPG Warm White 5 Watts x 2
    Cree XPG Neutral White 5 Watts x 6
    QUANTUM EPK7 - Violet -3Watts x 4

    Gives you an example you will need 2x to cover your 1.2m

    LED Lights are still new to the industry and you will get heaps of chineese LED that do the same thing and look the part! However there is a reason these LED lights cost the money they do and that is the designs of a heatsink! a poorly designed heatsing will destroy the output of your led chip even if it is a cree chip! A 10W LED gets just as hot as a MH and it will have a "meltdown if that heatsink is not up to standard!

    as for the strips i think they more of a novelty and as MAD max said just go brittle and break !

    Stick to the big brands for LED lights such as PS, Radion, Aqua Medic, ATI for now and you will probibly save time and hastle
