  • Lower k MH bulbs

    Just asked this question on RC, but then thought I'd repeat it here where all the higher IQ types hang out
    Anyway -
    It's MH bulb changing time and I've been looking for some new 6500 k 150 watt DE halide bulbs, but there are none available locally, the suppliers have told me 6500k has pretty much gone out of production. They have 5100k, or 10,000k. I don't want 10,000k as i want the greater par of the lower k bulbs, does anyone know if 5100k is high enough for a corals requirements?

    Hi Alastair, Iwaski has just come out with a 150W-14K bulb, reportedly having more PAR than most 250W'ers. I don't know if they also have a DE version thoughBob

      Can you get ADA products in New Zealand? They make a 150W 8000K DE bulb.

          Thanks for the help guys, good stuff!
          It's really just an experiment to see if there will in fact be better growth with 6,500k, I'll trial it for a few months anyway, and part of the experiment will be to see what other lighting is needed to counterbalance the yellow.
          I'll also check into those Iwasaki & ADA bulbs, sounds interesting, and Cetled I've sent you an email.
