    Doesnt the sf4000 use lm301b diodes and dont those diodes have a lifespan of 50,000 hours? So my guess is this light might last 50,000 hours

    For SF4000, its lifespan is >55000H. But it also affects by many other factors.
    Oh Canada!

    Ah 301 b diodes eh buddy? I just asked a question, funny you took the time to give me a smart answer. But thanks looks like you were close.
    I asked on another site and recieved a really informative answer. Diodes loose power slowley. He sent me a link to his experiments.
    Hi spider farmer i have the sf4000 but its lost it brightness ppfd as half and the draw from the wall is 160w the dimmer is on full 100% all the lights are on could this be the drivers or dimmer its 2 years old thanks
    At what heights would you run the SF4000? I’ve seen slight stress at 18 inches in flower had to dim down to 75-80% but a very awesome light. My forth grow and I’m truly amazed thanks Spider Farmer!

    Have you add a fan in your growing room? If not, we suggest you add one.
