    Water cooled COBs

    I'm definitely interested in methods that might take a little extra time and effort.. Especially if it will keep the setup somewhat modular and not require cleaning of the cobs and cooling blocks. I've seen the website big blue saw, and the idea of custom fabricating something seems fun. It...

    Water cooled COBs

    @mahiluana have you had anything like this machined or built?

    Is the ViparSpectra Reflector-Series 300W LED Decent?

    I wish someone had told me this before I bought my viparspectra.

    chilLED: water cooled, ducted, or active led fixture

    Thanks for the kind words.. I can't wait to start putting pieces together. Do you mid sharing some features of setups you've run?

    Water cooled COBs

    @DIY-HP-LED , @mahiluana , @ttystikk How have you all gone about attaching cobs to the cooling bar?? I'm brainstorming a method that won't require glue... some kind of bracket perhaps? What are the methods available?

    Water cooled COBs

    Thanks for your input @ScaryGaryLed .. I have definitely considered the stuff you've mentioned. I mentioned in an earlier post, like you pointed out, that evaporating water can dissipate a lot of heat.. And i have toyed with the idea of using that evaporated water(enhanced by either an...

    Water cooled COBs

    haha yessss @mahiluana that is an awesome diagram.. Unfortunately the tent is too far away from the water tank in the place I live, so the heat exchanger is out of the question.. But I'm interested in the cooling tower..What are the characteristics of the cooling tower? Basically the idea is...

    Water cooled COBs

    Cool cool.. thanks again.. RIU is an awesome place! Could you list off some of the common methods of cooling, in case i haven't considered any?

    Water cooled COBs

    thanks @Shugglet , That's making me think that I would definitely need some active cooling of the reservoir If I want to keep temps near ambient, like yours.. I think the maximum size reservoir i could get away with, even outside the tent, is something like a 5 gallon bucket.. Has anyone tried...

    Water cooled COBs

    hey tty, thanks for the response.. This whole build has been driven by the need to fit into my current circumstances.. So keeping the cost low, working with available resources... these are high priority. I also will be in close proximity to the tent, so keeping the whole thing relatively...

    Water cooled COBs

    The goal isn't to get the reservoir to refrigeration temp, only to keep it below 75.. I'm not sure what exactly you're trying to say.. Refrigerators keep things cold.. This isn't up for debate lol.. It's a matter of whether the fridge has the capacity cool the reservoir to the levels needed to...

    Water cooled COBs

    Yea i thought of that, but the fridge is kind of small inside, and i was also concerned that the fridge might overcool the water and create condensation on the coolbar/cob assembly.. Will await ttysticks response..

    Water cooled COBs

    alright guys.. here is a design i sketched up last nite.. Given that I already have the mini fridge, which i don't really use, I'm thinking this setup might be a good way to keep things inexpensive and keep the temps in a perfect range.. LMK what you think.. too much hassle? Would a pump work...
