WHO's WHO in LED research??? 10

We are looking to support the most promising NEW research
in the field of bio-reactor lighting with LEDs.
If you are interested or know someone who may be interested in this project please contact us at;


Thank You for your time and help.

    Hi Alan
    It will be great if you can also post some blogs / articles etc about LEDs in bioreactor.

    I was hoping that someone 'out-there' would come forward with new or old information on LEDs to help enlighten all of us.

    Here are a few points to start a discussion with:
    1. 50 watts will power 1,000 LEDs.
    2. Some algae like (perform best) at ~440 and ~660
    um of wave lenght.
    3. Algae do not like bright light.
    4. Algae do not need long resting (dark) periods.
    5 ? You fill in the blanks......
    6 ?

    Explain why a PBR with a debth of 20 feet and a surface area of 43,560 sq. ft. and with LED lighting,top to bottom, is equal to _______acres of open ditch bio-reactors.

    dear sam ,
    using led for growing algae is a good idea as it saves more power reducing cost of production, as far as i know algaes growth also depends intensity of light, so the only question is whether led can provide same lux as cfl's.

    Aloha Alan,

    I'm currently working with OSRAM SYLVANIA for LED Light-relay to biomass. I plan to test their Systems in my PBR Prototype.

    Thanks for the update and lead for lights. I suspose you are flashing (or "Disco lights" as
    Andreas calls it) and useing ~440 and ~660nm wavelenghts. How long is their guaranttee?
