Thank you for the additional tips Jeff. I'm curious as to how you guys figured out the LEDs need at least 33V. Is there some calculation or is it listed somewhere in the product description?
So I found a MeanWell RS-100-48 (100W, 48V, 2.3A) for sale on evilBay for a decent price. I assume this will work well for what I need. There's also a 36V version for sale but I thought 48 might be better, just in case.
I also found the LDD (so I need 3 of them?) but do I need to solder these onto some kind of PCB driver board?
EDIT: Jeff: forgive me if this is a stupid question, but would I be able to use just 1 LDD if I connected the Veros in a series?
Ldd-HW's have standard wires so no board needed..
as to the rough voltage pg6 lists the V(f) at 85C and 1050mA of current will be drawn.
LDD's need about a 3V differential...
soooo 28.8 plus 3 is 31.8 round up ad add some headroom.. 33V
I'd still find a lower voltage ps. w higher amps.
400W 36V 11A Single Output Switching power supply AC to DC SMPS
you can power 12 Vero's w/ that...
Yes there are other ways to power them..
IF you want 2 in series remeber voltage adds soooo you'd need a LARGE DC power supply. To be honest in th range of being a bit err.. "dangerous' AND generally expensive.
Now you could, at reduced current due to driver restrictions on the Meanwells put 2 in parallel so the voltage stays the same but you need 2x the current since it will be "split" between the 2
so 2 in parallel on one driver needs 33V and a 1000mA driver will split the current to 500mA per chip..
using the highest ldd-lw at 1500mA you will drive each Vero of the 2 at 750mA..
The plus side is they will run cooler w/ more "lumen/watt" efficiency. The downside is less gross output and if one fails open ALL 1500mA of current will be directed into the remaining "on" chip.
Seee pg7 of spec sheet I posted...
Last thing.. W/ your setup you would need 4 Veros (2 sets) and 2 drivers.
The "savings" in drivers is only about $7.............but the cost of one extra Vero negates that.
