PROLIGHT LEDS

1 watt white Prolight LED, £4.00 *($6.40), https://secure530.sectorlink.com/led-bulbs...,
(Received and tested 12-31-04; spectroscopy performed 01-18-11)

* IMPORTANT: Pricing is accurate as of 01-18-11. Please visit the Currency Calculator for the latest currency conversion rates from British pounds to US dollars.

The Prolight LED is a new competitor to the Lumileds Luxeon Star LED that we've all come to know and love. The main benefit to the Prolight LEDs is that they're priced lower than the Lumileds product. The Prolight LEDs come from www.led-bulbs.com in the UK.

The overall light output appears similar to that of Luxeon Star LEDs, and the color is a bright, slightly bluish white. I'd estimate the color temperature of this LED to be approximately 6,900°K.

This LED is designed to be operated at 350mA.


Photograph showing all three LEDs together.

In the above photograph, the 1 watt is on the left, the 3 watt is in the center, and the 5 watt is on the right.


Test current is 317mA.
The LED has a very wide viewing angle of 140°, so I cannot
measure the light output with the instruments at my disposal.

The overall light output appears similar to that of Luxeon Star LEDs, and just like the above LED, the color is a bright, slightly bluish white. I'd estimate the color temperature of this LED to be approximately 7,100°K.

This LED is designed to be operated at 700mA.


Test current for this photograph was 725mA.

5 watt warm white Prolight LED, £TBA *($TBA), https://secure530.sectorlink.com/led-bulbs...,
(Received 12-31-04, tested 01-02-05)

The Prolight LED is a new competitor to the Lumileds Luxeon Star LED that we've all come to know and love. As I already stated with the two LEDs above, the main benefit to the Prolight LEDs is that they're priced lower than the Lumileds product. The Prolight LEDs come from www.led-bulbs.com in the UK.

The overall light output appears to be a very, very slightly bluish-white in the center and a very, very slightly brownish-white toward the edges. I'd estimate the color temperature of this LED at the center of its beam to be approximately 4,200°K and at the edges to be approximately 3,600°K.

This LED is designed to be operated at 700mA.


Test current for this photograph was 709mA.
The LED has a very wide viewing angle of 140°, so I cannot
measure the light output with the instruments at my disposal.


I am not equipped to measure voltages with the test leads I have at this time; which is why you don't see them here. I ordered a set of spring hooks from Radio Shack on 01-02-05; I'll test the voltages when I receive them.


***VERY IMPORTANT***
The metal core PCBs these LEDs are mounted to are NOT sufficient for heatsinking purposes!!! You'll want to mount these to a metal surface with significantly greater mass before driving them anywhere near their rated current for more than ten seconds or so!!!



This was the last web page I published in 2004.

Do you manufacture or sell an LED flashlight, task light, utility light, or module of some kind? Want to see it tested by a real person, under real working conditions? Do you then want to see how your light did? If you have a sample available for this type of real-world, real-time testing, please contact me at ledmuseum@gmail.com.

Please visit this web page for contact information.

Unsolicited flashlights, LEDs, and other products appearing in the mail are welcome, and it will automatically be assumed that you sent it in order to have it tested and evaluated for this site.
Be sure to include contact info or your company website's URL so visitors here will know where to purchase your product.
