rosswaa Posted July 21, 2015 Author Share Posted July 21, 2015 Would that mean if I ran 2 cobs on the 150w driver they would be running at 700ma each? Then 3 would be around 450ma Would that be a better option than running them at 1.4a each in a smaller space I'd only be looking at running 2 for now Link to comment Share on other sites More sharing options...
Badders Posted July 21, 2015 Share Posted July 21, 2015 (edited) LEDs in this case are a constant current device and as such needs a constant current power supply; the LED driver I mentioned will always output the same current providing you adhere to the maximum stated output voltage. For example, MW LPC 150 1400 - the Max Vo is 108V. it will deliver 1.4A between 54 -108V. beyond that range it will probably just shut down. Its not recommenced to run cobs in parallel; and few people do in practice. 1 driver for each cob is okay, but the wiring gets messy, its even more kit to set up, and likely less efficient to boot. I'm running 4 cobs @ 0.7A in series from 1 recom 100W driver, by box is 1.5 x 1.5 ft - Edited July 21, 2015 by Badders Link to comment Share on other sites More sharing options...
rosswaa Posted July 21, 2015 Author Share Posted July 21, 2015 Got any pics? Link to comment Share on other sites More sharing options...
Badders Posted July 22, 2015 Share Posted July 22, 2015 if you have a look in the thread I started there are some pictures in there, Lean Mcsheen and kytaez also have pics of their builds. Link to comment Share on other sites More sharing options...
rosswaa Posted July 23, 2015 Author Share Posted July 23, 2015 (edited) If i got a MW CEN-100-42 Would it run 2 vero29s? I know it'll run the one and it's adjustable which would be handy I could just dial it down to suit Actually if there is an equivalent recom driver it would be easier for me to get one of them. I could get it all from one place Edited July 23, 2015 by rosswaa Link to comment Share on other sites More sharing options...
Badders Posted July 23, 2015 Share Posted July 23, 2015 (edited) MW CEN 100-42. ==== Max Output Voltage = 42v Vero 29 Voltage = 38V. * 2 = 76V. that driver will not operate 2 vero 29's. (unless you run them in parallel) You need a driver which can supply min 76V from recom you could go for -- RACD 150 - 1400 / 1050 / 700 hope that helps dude!

Badders Posted July 23, 2015 Share Posted July 23, 2015 if I was was your I would do it like this; 2 x vero 29 1 x recom racd 150 1050 (150w) 2 x AC a11 heatsinks 5v ac - dc power supply for cpu fan. only thing with recoms is they need a 0-10v signal to dim them, most MW's allow for a pot which is cheaper and simpler to implement.

rosswaa Posted July 23, 2015 Author Share Posted July 23, 2015 Think I'm going with 2 vero29s 2 of these drivers Input Voltage: AC: 110-265V 50/60Hz Output Voltage: DC: 20-39V Output Current: DC: 1500MA±5% Output Power: 50W Max Water Proof: IP66 And whatever heatsinks I find What driver would you recommend for the CPU fans? Only want something cheap Needs to be a budget build Link to comment Share on other sites More sharing options...
Badders Posted July 23, 2015 Share Posted July 23, 2015 phone chargers normally output about 5V, check the casing for the details. I used one for a few months no problems Link to comment Share on other sites More sharing options...
rosswaa Posted July 26, 2015 Author Share Posted July 26, 2015 I've picked up 2x Arctic 11 pros. And a wardrobe. I've started a grow with an Arcadia small led lamp and a 2700k cfl which will be changed next week when IV got the veros set up. From there I'll work on the wardrobe to get it stealthy etc should give me more headroom when needed Link to comment Share on other sites More sharing options...

op8 Posted April 7, 2016 Share Posted April 7, 2016 Sorryto but in chaps but do any of u know of a supplier of vero 29 or high quality COBs in general that does not charge crippling p and p on small orders pease? Link to comment Share on other sites More sharing options...
