Product Details

High Power White LED 3W with Heatsink & Driver 3 Pcs.

Create high power lights with the High Power series of LEDs. This LED assembly features 80 lumens of output and a 160° viewing angle. A low power requirement allows you to build an array that sips current, for hours of use. Three LEDs, one heatsink, and a regulated voltage driver are included in this kit for quick prototyping.

Specifications: • Size: 0.79" dia. x 0.31" H (20 x 8 mm) • Lens color: Water clear • Forward current: 700 mA • Forward voltage: 3.6 to 4.0 VDC • Viewing angle: 160° • Color temperature: 6000 to 7000K • Luminous intensity: 80 lumens (15000 mcd @ 160°).

Note: Do not stare directly into LED when in use. Do not apply power to this LED without a proper heatsink in place.

Rated 5 out of 5 by from Great little kitI recently purchased a few of these to play around with to see what i could do with them. Kit advertized with heat sink compound included, but was not. Had some available so it was no biggie.Parts are well made with LEDs installing easily on heatsink in the predrilled holes. The driver is a well made piece from Sure electronics and drives the LEDs silently.Testing: used a range of input voltages from 10v-32v dc with various results. With 12vdc, LEDs were bright and drew almost 600mA from benchtop power supply. Bightness or intensity increased until 16v where it seemed to stabilize with no further change. Ran the assembly at 24vdc, drawing 350mA for 12hours without issue and measured around 130 degree f on heatsink with a thermal imager. LEDs are signicantly warmer at around 190f.Overall, a great little kit with some fun uses. If you wanted to, you could ditch the heatsink and attach the LEDs in a longer line to some alluminum rail. I made an aluminum frame to insert the heatsink into then installed a portion of flourescent lighting troffer over the LEDs to help disperse the light. Color of LEDs are toward the blue end of the scale.

Rated 4 out of 5 by from Good, could be great.This is a decent kit that with a little refining could be really great. It does not include a power supply, only the current driver and comes with NO DIRECTIONS. Furthermore there was thermal grease included tho I was told it was. With an LED circuit simulator I was able to determine that 12 VDC would drive this array without the need for a high power resistor however the data sheet for the driver gives a vague 9-36 volts which is the capacity of the driver not necessarily the emitters included in the kit. I also have a 24V power supply that I may try, but I think its going to be too much for only 3 emitters (watch for the flash and blue smoke)... Another minor annoyance is the lack of mounting consideration for the current driver. The heatsink is only drilled out for the LED stars and with the terminal blocks soldered to the board the driver would short out unless it was insulated from the heatsink with standoffs.With a power supply, a simple schematic, and mounting consideration for the driver this would be a GREAT kit. The price is nice, and it is simple to put together (if you know how the circuit goes). I built the whole thing in 10 minutes or so. Some optics or a reflector would also make a really nice addition!

High Power White LED 3W with Heatsink & Driver 3 Pcs.

Is a resistor needed or supplied?

Does this need a resistor between the last LED star negative and the ground or does the negative just go back to the driver?
Asked by: ATJohnson
The negative goes back to the driver.

What power supply is required for this?

Would this 24VDC power supply work with this? http://www.parts-express.com/pe/showdetl.cfm?partnumber=320-314Also, do you recommend any reflectors or optics to go with this? What about thermal compound for the heatsink? The provided docs only cover the DC-DC power supply/Driver
Asked by: ATJohnson
This will take an input voltage from 9-35VDC. As a DIY kit, the reflectors are not something we offer separately at least yet. Heat sink compound is included.
