    Default LED Lighting?

    I just recently moved to my new home and will have to grow my orchids under lghs instead of windowsill light. I have each plant a MAX of about 14 inches from an LED light with a color temperature of 6500K. My plan is to do 12 hours of light per day. Do I need to worry about burning my phals and paphs?

    Not enough info' to give a useful reply. I have one LED light, but it is a horticultural grow-lamp as a substitte for the 600 watt growlamps I also use, and the LED has a whole array of individual lights totalling 240watts. I also use a lightmover, so that the lamp comes and goes over individual plants to avoid burning.
    I would think that if yours is a 2.4 watt unit - and 3 of those lights my shaving mirror very brightly, you might be ok . But hard to be sure.
    Try it out. If the leaves start to turn red it is too much. If the plant does not grow visibly within a week, itis too little.

    Thank you Geoff. There are two, 4 foot lights per fixture and each fixture uses 40 watts. So each plant is under a 40 watt fixture. Not sure if that is helpful, but I will take your advice and watch for signs of too much light or lack of growth.

    Traci:

    1. Is the wattage actual or "equivalent"?
    2. What plants are what distances? While 14" might be fine for some, it might be too far for some and too close for others.
    3. Are they plant lights, or home lighting re-purposed?

    FYI - in fluorescent and LEDs, color temperature doesn't really tell you what the spectrum is, as it is a "correlated" or "corrected" color temperature - corrected so it "looks like that" to the human eye.

    Also, be aware that one reason white LEDs look so bright (as Geoff noted in his bathroom) is that they are very strong in the green part of the spectrum, which happens to be the human eyes' most sensitive part of the spectrum.
