And it seems a rather well-made driver,also...I have one of these on the way for testing. I am expecting a lot less than 2100mA but we will see. If it delivers anything close to spec, it will be a popular driver.
So....maybe i have to find something with current output at 2.5-2.8 amps it could be better?...if i understand well...i'm elecrtrician...i'm not working with elecrtonics but i can figure it out... something like that?http://www.globalmarket.com/product-info/120w-led-driver-42-5v-2-8a-saa-pse-619424.html Vf could be at 40v? (of course if i can find something with output current at 2.1 amps and 100w at 40 v it could be better).Thanks for you advise!!!Time to go to work cables and fuses need me.Good find akaki, if that driver actually outputs 2500mA or so it would be a decent deal and possibly a good match for the Vero29. But if it puts out 3A, the Vero 29 vF might want to be a bit higher than 40vF.
The Vero 29 performs better than most at high currents, but just like all LEDs it performs more efficiently the softer you drive it. At some point, it becomes cheaper to run a pair of them softer rather than run one very hard. Then of course there is the savings in electrical cost, which help pay for the increased up front cost over time. This is especially true with grow lamps and even more true if you have very high electrical costs in your area.
BEST MATCH....The absolute max drive current of the Vero 29 is 3150 mA, but imo it's better to stay at 2100 mA or below. A good and dimmable driver is the Mean Well LPF-90D-42.

Mouser is very expensive. I've been looking at the CEN series for the '29. Metal case and adjustable voltage and current.47dollars for one piece?mouser sold it 70e?strange
yes dicit 47 dollars was from jameco.com but is this site shipping world wide?Mouser is very expensive. I've been looking at the CEN series for the '29. Metal case and adjustable voltage and current.

That's a B on my name not a Dyes dicit 47 dollars was from jameco.com but is this site shipping world wide?
oops!!!!the writing of a stoned person....i will contact with them i think for my country there is no import taxes under 100euros so with 2 of theme i will be ok.That's a B on my name not a D
Not sure I'm following. Coffee may be kicking in. However yes, jameco offers international shipping.

so...if the current output is bigger Vf becomes bigger too?Good find akaki, if that driver actually outputs 2500mA or so it would be a decent deal and possibly a good match for the Vero29. But if it puts out 3A, the Vero 29 vF might want to be a bit higher than 40vF.

sorry supra one more question...the driver that i will use is the meanwell lpf 90d 42.thats correct, you can see the vF graph in the vero pdf, although it will vary from chip to chip and to complicate matters, vF decreases as junction temp rises.
In most cases it will be a pair of wires. Some drivers need a signal from something like an arduino (PWM). Others will allow you to wire in a potentiomer to control it. I have limited experience with the PWM but I have used a meanwell that used a pot, and it was pretty simple.sorry supra one more question...the driver that i will use is the meanwell lpf 90d 42.
in the datashit sais."Using the built-in dimming function on LPF-90D can't turn the lighting fixture totally dark" is any dimmer switch /screw on the psu?
