    DIY: SSL complete protection for two LED drivers

    I just meant safer, as in compared to a newb making his first soldering attempts on creating an AC line. Not questioning that what you came up with isnt great stuff or isnt superior. Was talking about something like this...

    LED vs. HID Double Ended Bulb

    Can you confirm that in agri greenhouse led lights have to be ip65 rated, Jet of waterstream resitant? That 50W design light for about 2000$ with passive cooling guod posted came to my mind ;-) I know it was a "design" thingy...but the heatsinksystem needed there seemed large

    LED vs. HID Double Ended Bulb

    I asked someone who "said" (cant prove it) he works in that industry and he told me: -Initial capital Investment for quality IP65 (means to be able to shower with it) Led lighting is still too high -dual electrode HPS can use pre existing ballasts, which means nice gain and low Investment costs...

    Insight: Amare Tech Solar Spec LED Panels

    I thought it would be finally over. For me that has nothing to do with honest reporting, seeing you mentioning it every 3rd post. Typing spydr into search and your name, confirms that you are overdoing it. (166times) Actually made me hate it.

    COB spectral research microcab

    even my chinese WW/R combo gave one plant standing in the middle 3 albino bleached tips. Completly green besides that. I raised the lights and (dont know how long) later it was gone/ hidden edit: but my light is symmetrical and other plants were unaffected, so I think it might be straindependant

    LED vs. HID Double Ended Bulb
