    Hey all - just go me a new lighting unit with 3 x 250W MH (14000K, 2 x 20000K) and it has 2 x 9W G23 CFL in it, Julian reckons they need replacing, but all I find is the low K bulbs - anyone know where I can get the 6500K CFL 2 pin bulbs from?

    Wow, that must be a mother of a unit. Got any pics ?

    Contact Donovan at VIP, he will advise on what is available.

    Very nice. Have you though of maybe retro fitting T5's, going do a better job than CFL's

    Hmmm, thought about that, and what I thought I'd do, considering this units only 330mm wide I would get a T5 unit with 4 x 80W actinics to sit alongside this one

    But then again, wont the 2 x 20000K and the 14000K plus the 2 x 6500K CFL be enough?

    I am not sure what sort depth penetration you going get out of the CFL's

    Their L rating means you not going use them for colour, so you may find them a bit of a waste, other than some of the corals, mounted higher in the tank.

    The 20000K MH's will give you good colour, but you would need to run them, your entire lighting cycle (10-12 hours)

    If you had 2 x 22000K T5's either side of that pendant, it would give you plenty light @ colour for "sunrise-sunset" phases and then the MH's kick in for a 6 hours "midday" phase.

    This is my opinion, keeping in mind, I have no idea how effective those CFL are ;)

    Great feedback Warr, that why I thought about the additional T5's in the Actinic range - still looking at it and will feed back

    taking this tank build WAY slow - have my 1.2M baby going and want the 1,8M perfect before I break it down and get the corals across

    Why dont you try actinic cfl, it might give your corals that nice glow. I know VIP has them.

    Marc - also contact "The Lamphouse" and find out if they might some of these PC globes. These are not CF globes mind you. They are PC globes.
    PC = Power Compact Fluorescents
    CF = Compact fluorescents

    Jacques, it tells me that they are the 9W G23 Compacts - so these are the Power Compacts? Google seems to think it is both?

    I am baffled.....

    Warr / Marc - Compact Fluorescents have a completely different fitting, than Power Compact Fluorescents...

    Power Compact Fluorescents are basically a T5 bent double. CF globes are VERY low output flourescents. It's like comparing T8's and T5's.

    There are LOW output T5's as well.....

    According to my research they are T4's - yes bent over - these are 9W - so I am guessing low output and in the UV range? Odd

    Marc - therefor PCF = POWER Compact Fluorescents.... a completely different horse altogether.
    The Boyu/JBJ nano's come with PCF globes.... not CF globes....
    And they are 18 and 24 watt's....
