    On the Nano I built up last year, its almost time to do a globe replacement. The PL tubes 36W is R150 to R270 each. So R300 to R540 twice a year.

    With LEDs being the in thing. And I know I'm very sceptical in the benefits of LEDs. Especially in regards to light spectrum and penetration. They are the future, sure, but is that future already with us.

    OK with that said. What is the most cost effective LED option on a Nano Cube 24G, a 80L system. I cannot justify spending 3 or 4 times more on the lights than what was spend to get the cube up and running. The cube is basically a softy tank. Mostly Zoa's and some rics. Most difficult coral is one small Pipe Organ coral (LPS) that like deeper water anyway.

    Loosing the hood is an option. But hanging the LED unit from the ceiling not. DIY route is also an option, although electronics and me do not work so well together.

    So options please.

    ok so without shipping and possible import tax, that is just shy of R2000.
    And I have to master my soldering skills.

    any other options?

    The rapid kit looks like a good option Riaan not difficult at all to assemble! Ill even put it together for you if you want!

    Wow, that is a really good price. Is there a calculation to work out how many watt's of LED's you need? If I wanted to replace 150W MH with LED's what would I be looking at?

    Hi RiaanP

    TSR is running a special on solarmax 36 Watt all Aluminium LED units which are perfect for small nano's.

    Selling price R1899

    They are also proven LED's as we tested at the shop with good results.

    @Submariner in your opinion is that unit enough to replace a 150W MH?

    I currently run 4x24W T5's for 9 hours a day and a 150W MH for two hours midday, I want an LED unit to replace all of it.

    We have done par reading on these LED lights and the performance was on a par with with a DE 150 watt MH

    What is the spread like? My tank is 700x450x450, my main concern is that a single unit will not offer enough spread for the entire tank.

    Hi Silverza

    You will need two units to cover that tank with the standard lenses.

    if you take the lenses out you will get better spread but obviously less par.

    We will also have different lense in stock soon.

    Hey Mandarinman - you are right, especially when it comes down to the nano tanks, but this unfortunately doesnt work out cheaper for the odd shaped tanks and tanks that are large...

    DIY it with cree XML's... XPG's are the old tech now. The XML's have more power and better energy efficient. You can pump these things up to 3A and get 1000 lm out of each of them. They will last way longer than the T5's and MH. It seems pretty obvious to me.

    Been reading a fair bit and it appears the Bridgelux LED's are slightly underpowered compared to the Cree LED's. It' pretty much a 3:2 ratio. If power saving is your main goal the Cree's are definitely more efficient, for a lower initial investment the Bridgelux seems a lot easier on the wallet though. The Cree's will end up paying themselves off within the first couple of years though.
