    So about a month back i ordered a couple of super cheap AC cobs, just for fun really, thought I play around and see how they work.

    I forgot all about the order and it finally arrived yesterday... 1 month to get from the UK to the Netherlands. tjah!

    In my box I have a few old video card and CPU coolers, you know how it is, and also a few old Phone chargers, you know how that is too i guess.

    The AC Cobs are not very efficient i think, but one has to have a little fun now and again.

    I think it will work out fine for seedlings, rather than blasting them with 10 x 1212's

    thanks, it was just a quickie, took about 30 mins to find the bits and put it together, all from old junk sitting around in the box/shed/storage, Video card coolers have larger thermal plates than most CPU coolers so seem a better option for these cheap cobs. running quite cool, 24.5 right on the thermal plate, barely above body temp 5 cm under the light. at this rate I might try without the fans see how it warms up.

    I know all the old stuff I keep is for a reason, but I might be a hoarder and that's the only reason.
