What Cree LEDs are Compatible with which Drivers??? Nano-cube-24

[Sir Pat]

I have 2 drivers-

Meanwell LPC-35-700

and

ELN-60-48P

Which cree leds, preferable those available from rapidled.com in the solderless variety, are compatible with each of these drivers?

Are blue and white leds able to be ran off the same driver? Or do the blues and whites need to be ran off separate drivers?

Ive got the kit for my nano cube 24- just need the leds and a dimmer. Can use either driver.

Cree X Series LEDs can can be mixed... for a 48VDC Driver 12-13 is a good number.

Personally I prefer the LDD Driver as it can be dimmed down to 0 with a Storm Controller...

Be Careful with the Glue as to not damage the LED with spill or cyanoacrylate fuming when securing the optics...

Ok, so the common config for driving LED's is to use a "Constant Current" driver. This means that driver will output an exact constant current, while the voltage becomes the variable.

So what you do is you run all your LED's in 1 series circuit. Because Voltage is constant in a parallel circuit & current is constant in a series circuit.
So the main thing you have to worry about is the current. & Voltage Range will tell you how many LED's.

You could get some 700mA LED's and drive them at Maximum Current from your LPC-35-700....
Lets say these LED's you choose run at 12VDC.
Well the Range of your LPC-35-700 is "Range (VDC) 9~48VDC ".
So, on that driver you could run (1-4) 12V LED's in series. If you used only 1 then the driver will provide 12VDC (~8.4W). If you run 4 LED's the driver will provide 48VDC (~33.6W).

Model Input Output Dimming Dimensions(mm) LPC-35-700
Range (VAC) 90~264VAC
Freq. (Hz) 47~63Hz
***.(Typ.) 85% 88%
Current (mA) 700mA
Range (VDC) 9~48VDC
Power (W) 35W
R&N(mV) 200mV


ELN-60-48

"Mean Well’s ELN series runs off line voltage (90~264VAC) and has a built-in constant current limiting circuit with adjustable OCP levels. The ELN LED driver series comes in 30 and 60 Watt models in which you can change the output voltage and current with internal potentiometers. These drivers come in a fully isolated plastic case that is IP64 rated. The wire connections use UL rated 2-conductor wire with 18AWG. If you have specifications and standards for your project, you should know this is a class 2 power unit. This LED driver will allow you to adjust the output voltage and current ranges to your needs, adding a versatility you can't get with just your standard driver."

As you can see this driver has potentiometers that allow you to manually adjust the current and voltage.

Forgot to mention

The Cree XT-E is 1500mA Max

Generally its best to drive at satin or 66.6% of max current...My Apologies For Those Superstitious...70% is also industry standard...After this the heat is exponential and unless dissipated can lead to lower intensity...This is why thermal management is key...Ensure the finished fixture is cool to the touch for optimum performance.

For the XP-E2 700mA and the XT-E 1000Ma is perfect.

Your drivers are good... My Experience is the LPC is Bullet Proof and the ELN about Three Years...

Thx guys-

Think I am going to go with 2 Solderless Cool White CREE XP-G2 LEDs and 10 Solderless Royal Blue CREE XT-E LEDs using the ELN-60-48P.

Are there any inexpensive manual dimmers compatible with this driver?

Thanks for the heads up
