    Bridgelux EB Series Build

    Sorry for lack of an update, just about finished up. Being "amateur night" had a few PH/nutrient issues As they got bigger, but was successful over all. Ended up with about 400% stretch (far red helped?) and pretty much ran out of room, top colas end up about 4" from light.I will post some...

    Bad EB Strip?

    Looks like you may have broke the solder mask, shorting across those two copper planes, which provided the full/higher voltage to those LEDs? Also, I would only use the screws near the edge for mounting. If you look at the copper it is pulled back around those for this reason. The hole that...

    Bridgelux EB Series Build

    I've used mine seedling all the way through flower with 9 strips. Starting over, I would have wired it up to only run the center strips (use a switch of the outers as they get bigger during veg) and dim them as needed. You can run these as close to your plants as they will tolerate as they...

    Bridgelux EB Series Build

    I appreciate it it, you guys have added a ton on info/research on these things since this thread started. I'm less concerned about even temps as all my strips are individually driven by their own LDD-1000H, so even if the strips have differences, it won't effect the others.

    Dead center in my fixture on backside of Al Sheet ihave DS18b20 attached with aluminum tape. So not really a dead accurate measurement, but should be close enough.

    Naming this grow "Amateur Night" on account of my first grow and the strippers. Finally some photos: Tent currently running @ 900ma ~12" from canopy. GSC on left : OG Kush x NY Diesel on right Light holding steady @ ~76F with 3 fans (one above, one aimed above canopy, and one at ground...

    Bridgelux EB Series Build

    Sorry for disappearing on the thread. Its working out pretty well. (nothing to compare it to as this is my first attempt). Light staying around 80F @600ma with 2 fans blowing around (+vent)in a 48x30 tent. Running in a basement in the low 60s. Vegged for 6 weeks @600ma (24/0) and just flipped...

    I was looking for the values you posted before just to approximate/interpolate mine. Could you poste it to pastebin?

    Bridgelux EB Series Build

    Finally got some solid logging code running on my ESP8266, dumping data to ThingSpeak every minute. Light temp dips due to a bug/lazy coding on my part reading all the DS18b20's. Sealed Tent Running @ 500ma. Air/Humidity temps are near the floor currently (working on mounting higher). Canopy...

    Finally getting around to actually growing something with this, do you have the PAR values you posted? The image issues on here won't show it. Just looking for a baseline mine ~x2 your values (9 strips vs 4 strips)

    Bridgelux EB Series Build

    Been real busy with work, minor update got the two Far Red XP-E x6 PCB's mounted and powered. Been working on enclosures for light wiring & controller + sensors. Was having trouble getting RTC running on ESP8266 for lighting scheduling, so I broke down and bought 2 way Outlet timer. Got a very...

    Or get a Toaster Oven and a dispensable solder paste syringe and do it yourself.....although can't beat that price.

    On/Off functin for meanwell HLG style drivers using dimming and arduino

    You also need to keep in mind the efficiency drop of a AC/DC(SE-450-36)->DC/DC(LDD-1000H) vs a HLG Driver. I ran into this on my EB Series build. The SE-450-36 is 88% x LDD-1000H 97% (~85%) vs. a HLG Driver of ~94%. You do get the easily implemented PWM digital control (and some initial cost...

    I'm using DS18b20's: https://www.amazon.com/Vktech-DS18b20-Waterproof-Temperature-Transmitter/dp/B00CHEZ250/ref=sr_1_cc_1?s=aps&ie=UTF8&qid=1484969866&sr=1-1-catcorr&keywords=ds18b20 You will need some sort of controller to run them off. I am using an ESP8266 running MicroPython. Setting up my...

    Bridgelux EB Series Build

    Got around to soldering my Far Red XP-E's onto my sample PCB's. Been looking for an excuse to try out toaster oven soldering. Used the end of tube of tin-lead dispensable paste I was able to rescue from being tossed at work. Tested one of the 6up strings all the way up to the max 1000ma drawing...

    Hooked up a 4" flexible exhaust and inline fan (~65CFM from HD) out the top of tent. I opened the bottom vent on the tent. Temps look like they lowered ~6 degrees. Air temp staying constant ~24C/75F. 49C: Backside of LED #6 in center of fixture. 44C: Top of 1x1" aluminum rail on long side...

    Bridgelux EB Series Build

    Not at all, if anyone was looking at starting a similar build they should be using the the Samsungs for the price/eff. Started this trying to make a cheap, mid-power, evenly spread light I could and looks like its getting cheaper with everyones research.
