@FranJan Alright with cooling the hans , when flower position on , the panel are getting hot , i know the led are less efficient. But its just by the top of panel , not towards plants , which is not bad . And yes , fans blowing the panels and the temp decline pretty easily. Yes , i was...

ok , thanx man , i change the setup , and put like i said hps in middle and panel on left and right. The temp is better now but always with the clim I just hope , i 'll dont have kind of umbrage zone due to the panel's tilt ( or angle ) on the side and the hps in the middle ( hps is at 60cm from...

Hello all :) Actually, got 2 hps 600W running in a box L 1.50m - Wide 80cm - tall 2m with a mobil climatisation which blow cool air in front of the box , ( the box is open so ) , temp is above 28-30° . Due to high temp just outdoor ( more than 35° ) i would like to remove one hps , and put...

does the connectors are ok for a vero29 [email protected] ?? http://www.digikey.com/product-search/en?mpart=0688014226&vendor=900 there is so much model for these pico , cant find something on datasheet .....

Hmmm , little exercic in question form please : Just for example , -driver 1 CC output 84V max ; 2.4A max non dimmable -driver 2 CC output 84V max ; 2.4A max dimmable -driver 3 CC+CV output 84V max ; 2.4A max dimmable on V and A -driver 4 = driver 2 and 3 but multi channel option Now if we...

Helllo , I think you need more something like power supply ( ??) look like this : http://www.ampoule-leds.fr/bien-choisir-son-alimentation-special-led.php its in French but looks at middle of the page the 2°) paragraph I seems to me I already saw some of this driver with high V and high A...

Yeah , thats why there is a some much questions about Led If you want to buy a commercial lamp , you gotta know so much things , and if you want to make a DIY , you gotta to have good eletronic notion , which isnt the case of ppls. Guys the time to know , that needed to we gotta look at the...

Hello , dunno if it was post ( if it was than sorry for repeat ) There is a lot heatsink solutions for lot of COB , start ect , and display by series , bridgelux vero ect , cree cxa , citizen ... http://www.led-heatsink.com/ I think to cool the vero29 I'll purchase I will grab this one...

For the vero29, this meanwell looks ok right ? http://fr.onlinecomponents.com/mean-well-cen10036.html?p=37809805&ref=octopartfeed you learned me something about the temperature at start up^? So if its cold , the vero needs more voltage than 36V ok , but this driver first, has an Voltage adj...

When you talk about buck puck , you mean this things like this ? http://www.taskled.com/techhboost.shtml Becuz the thing can outp 80V @ 1.5A it seems

Haha , ok , I'm not totally disappointed lol ... So the 48V model is better than the 42 even the 48V got 1.88A So after read the graph datasheet , the vero29 at 1.88A should run at 40.5V~ ??? Hope I'm correct

ok for the vero29 my bad , but for the driver ? How can it provides 2.2A as the max is 1.88A ? Even if 5% tolerance , it provides 940mA more ...

Guys , I am SO lost .... Definitively there is something I really didn't understood . Thx Supra and others for explications but , with my poor English and technic vocabulary ... you know .... Here I found someone who have post on another forum, he run single vero29 with this driver : Mean Well...

hey guys n what this kind of driver ? I can see there is emplacement for the led wire , the dim conector , but how do you power this thing ? With an universal transformator ? anyway outp volt max 80V , available at 1.5A or 2A and dimmable... could be fine for cxa3590 ? cuz its 40$ , so not very...

ok guys I get it :) Anyway I will go vero29 , I just post cxa3590 config for someone just in case . Yeah for the fan I would habe been going on dynatron like JavaCO Hmm I miss something with V and A the V is automatic adjust by the driver right ? the right voltage depends on the A current...

Well , here I am for cxa3590 module -4x http://www.digikey.com/product-detail/en/CXA3590-0000-000R00BB30F/CXA3590-0000-000R00BB30F-ND/4501398 or 4x http://www.digikey.com/product-detail/en/CXA3590-0000-000R00AD27F/CXA3590-0000-000R00AD27F-ND/4501389 or 2x bin BB 3000k + 2x bin AD 2700k cost...

Hmmm , i think COB led is designed to replace HPS/MH in street light ect .. If you take a look at cxa3590 datasheet , you will that the 2700K have a big part of blue , and lot of green ect ... The peak in red is 620 i believe by memory ... And , in my opinion , i would make , and thats what...

Well if you mean the hlg-120h-1400 , like JavaCO and others said, it'll cost 70$ per driver. on 108V output , you will use 84V max for a 108V output driver , which isnt the best ... but read some post you will see . For the cxa3590 , read some post again , there is not a lot of choice . In 3000k...

@SupraSPL Wow , this story with with Sure-display really sux dude:/ But like I will say , the cxa3590 cost too much due to the driver .... Hello JavaCO , Thanx for the help :) Yeah , after months research , for the cxa3590 (77V) solution , well I will buy Chinese driver, found by Positivity...

haha, God bless his balls :) Its just I don't trust in Chinese stuff , more about electric material. Sure its supposed to works fine , your home wont gonna burn and no one will go die, BUT , its usually shit stuff , like if you buy some 125cc Chinese and go on road withtout verification, you...
