oh i guess the 50v volt drivers at 700ma (35w) would draw about the same wattage at the 36v at 1.05 amps (38w). That works out to 75-80 watts per heat sink, I want to keep the power draw relatively the same as my current setup and just increase the amount of photons. That being the case maybe...

No they are in ideal holders.. the pictures are old.. the heat sinks can handle something like double what i have on there right now.. i can run them passively in the current setup but the fans are dual purpose.. they are 3000 rpm industrial fans that move enough air that i don't need anymore...

Thanks for the reply.... I'm a machinist so drilling holes is no problem... Its 4 heats sinks with 2 chips on each, so 3 chips per driver doesn't work for me.. The chips are top bin CXA3070 3000k AB's. I also have some other Z4s I put in a drawer a long time ago because I thought they were to...

hey @CobKits, I'm looking for a recommendation for upgrading my almost 3 year old CXA3070 setup... basically I want to reuse my 4 heatsinks and drivers and just change the cobs/holders... Currently I have 2 HLG-185h-c1050 drivers running 8 cxa3070 on 5.886" heatsinkusa profiles. What is the...

@CobKits Are the 3000k 90cri gen 6 1212's still 36+/- volts? and how to they compare to the cxb3590 3500k 80 cri?

For sure I was looking at the old one... its the first one that pops up in a google search.. so the new ones are 50v minimum..shitty.. I've been gone from here for about 2 years now and i figure its time to upgrade my setup.. you can see it at the link below...

When i look at the spec sheet for the cxm22, on page 6 it says the typical forward voltage for this is 35v at 1280mA http://www.luminus.com/products/PDS-002437-Rev01-CXM-22.pdf Also the cxb3590 is a 36v chip...

OK I havent posted in a while, been busy but thought I should update everyone. My prize pack from @Midweek Song came today, except for a little panic on my part the package arrived quickly and as described. The $100 actually came out to like $115USD when I typed in the code and they through in...

well you lost my vote.;-) Thanks to all the sponsors, ignore this guy he doesn't speak for us all.

I'm just waiting for a nano v3.0 to arrive so I can finish off my 4 relay timer project box V1. It will control the lighting and flower initiators of the 2 tents and keep them in sync. V2 which I am almost done the coding for will be a later upgrade, it will have the option to set the time and...

@Gadgetboy Usually if you're going to be working with the little guys people buy them already reflow soldered on to stars. You can do it yourself with a sinkpad or similar product but it requires a little more skill, equipment and a stencil specific to the chips you have. I have never done it...

I have problems with the current version of fritzing in debian stable so I don't use it. This new version seems to run much smoother than the one in the repos, I just downloaded and extracted the tarball, ran ./fritzing and it all seems to work pretty good. I will test it out, I hope it works...

I take a second run at it, I'm sure I've got some more seeds rolling around loose in that drawer of champions.;)

So I think I have everything ordered for my arduino based e-nail project, I got the coil and xlr connector from gimido everything else is from from ebay. I try to get everything from the same store so they would all arrive together. 25A Solid State Relay for turning the heating coil on and off...

With all this arduino info salm, I think with the e-nail I'm building, instead of buying a pid controller I should attempt to arduino myself one. The gimido heating coil arrived and I have a few arduino clones that came also, I still need to pick up a SSR but I have a magnetic one that will work...

The 10.08 is one of HSUSAs worst designs for passive cooling, the fins are too tall and too close together. It is however a serious chunk of aluminum and will work great with only the slightest amount of air movement. The 10.000" and the new 12" profile they have listed on their frontpage would...

SDS, I love this stuff man. I have also been working with arduino for fading and controlling relays but with the TimeAlarms library and just using the 5v arduino signal and a circuit you posted for me months back. https://www.rollitup.org/t/diy-led-cree-cxa3070.789575/page-74#post-10695272 I...

My first tent was a secretjardin, what a piece if crap that was. Since I found gorilla grow tents I wont use anything else. They are way thicker, sturdier and taller than than any others I have seen available. I still use the SJ for veg but the poles have started to rust so I don't know how long...

I can always find a reason to build another light also.;)
