    Doing it with six hydrofarms SE with middling bulbs. 2 rows of 3 with a 1.75 foot aisle in a middle. I was thinking 4 QBs with 4 boards each. The middle row the two DEs.

    I know with 4 QB boards per fixture w two meanwells. Is there any juice left over for a COB or 5th QB.

    q
    Dude I am worried about digital ballasts send radio messages to aliens through my tooth filings. Do Meanwells have less RF?

    Theres no volts left the way i run them,2 x qb per mw 240-1050b i had to run a 3rd driver for cobs on the big panel i made.
    Far as i can tell the meanwells dont put out nearly the rf interference that other hid digi ballast put out.my op is alot less fuzzy now.

    I would imagine That Meanwell product meet RF suppression standards. Personally, I'm more interested in ways to jam networking over powerlines........

    I'm so fucking lost as to what you guys are even talking about. lol I'm assuming ballasts put off RF that the govnt can track or see or some shit? Can't imagine that would be a problem unless you're doing a huge op right?

    One shitty ballast fuzzing out the neighbors tv in an apartment can be enough to take a guy down ;)

    Got my 7.984" heatsinks and can report that they are only slightly convex so no need to straighten them, just going to hit them with some very fine wet sandpaper.

    Nice idea; so you're running hot water through the fixtures?

    They output DC current. No nasty RF.

    Some digital ballasts when put too close to cable boxes or cable Internet routers can cause RF feedback which can piss off neighbors and can send the cable company to your house.

    This is very true and happened to me. Just bring in the same house can be too close.

    Drivers for LED chips and boards output DC current, which has no frequency with which to interfere with cable or radio.

    Similarly, magnetic ballasts and the special low frequency ballasts used to drive CDM/CMH/LEC lamps are also EMI safe.

    It's the high frequency drivers that are the culprits, especially cheaply made and poorly shielded units.

    some of the cheaper digital ballasts have poor or no sheilding, even though its required by law ( good ole chinese crap )

    digital ballast also put out RF, they are just easier to sheild

    :peace: Yes 36°C before shower - after shower the temp. go down to < 20°C and the Powermeter
    shows me 3% rising because Tj is lower.
