LEDS INTERNATIONAL LED MODULES



This web page is for LEDs International LED modules.
They sent five modules; they will be added to this web page as time & instrument availability permits.



LEDs International, white LED module, BL-5W3L
Received 02-20-07, tested 03-23-07
This is a printed circuit board with 15 specially cut 5mm LEDs. These LEDs have a wide viewing angle; estimated at ~100. The LEDs on this PCB appear to be connected in series with a series resistor (five total on this board). The result is that if one LED fails open, you will not lose them all; only three of the fifteen LEDs will go out.


Here is the module itself. It is designed to be operated from 12 volts DC.

The light's color temperature appears to be rather neutral; probably near 5,500K, which is a very slightly coolish shade of white.


Measures 35,100mcd at an If (drive current) of 128.6mA.
Viewing angle appears to be ~100.
This is a wide-angle LED module, and if I've told you once, I've told you 1,000,000 times:
Wider viewing angles always, always, ALWAYS equal lower mcd values!!!!!!!!!

LEDs International, white LED chain, T0-6016
Received & tested 03-22-07
This is a string of ten printed circuit boards with nine specially cut 5mm LEDs per board. These LEDs have a wide viewing angle; estimated at ~120. The LEDs on these PCBs appear to be connected in series with a series resistor (three total per board). The result is that if one LED fails open, you will not lose them all; only three of the nine LEDs on the faulty board will go out.
There are a total of 90 (ninety) LEDs in this chain.

There are 10 boards containing nine LEDs each; these boards are connected in parallel to one another with insulated wires approximately 1.5" (3.8cm) in length. The boards are equpped with double-sided tape on the back, so you can affix them to any reasonably flat, clean surface - even a curved surface.


Here is the module itself. It is designed to be operated from 12 volts DC.


And here is one of the boards in this chain.

The light's color temperature appears to be just ever so slightly cool; probably near 6,000K, which is a very slightly coolish shade of white.


Because this is such a long string, I cannot measure the intensity with the instruments at my disposal, nor am I able to furnish a beam photograph on my usual target.

The If (drive current) is 537mA.
Viewing angle appears to be ~120.

LEDs International, white LED module, BL-SMDW
Received 02-20-07, tested 03-22-07
This is a printed circuit board with nine SMD LEDs. These LEDs have a wide viewing angle; estimated at ~150. The LEDs on this PCB appear to be connected in series with a series resistor (three total on this board). The result is that if one LED fails open, you will not lose them all; only three of the nine LEDs will go out.


Here is the module itself. It is designed to be operated from 12 volts DC.

The light's color temperature appears to be rather neutral; probably near 5,100K, which is a very slightly warmish shade of white.


Measures 5,016mcd at an If (drive current) of 75.2mA.
Viewing angle appears to be ~150.

LEDs International, white LED module, ML-5FSPW
Received 02-20-07, tested 02-21-07
This is a set of two printed circuit boards with a total of six super-flux ("spider") white LEDs (three per board). These LEDs have a wide viewing angle; estimated at ~100. The LEDs on this PCB appear to be connected in series with a series resistor (one on each board); one board is connected in parallel with the other. That makes a total of 6 LEDs.
The result is that if one LED fails open, you will not lose them all; only the PCB with the faulty LED on it will go out.


Here is the module itself. It is composed of two boards with three high-flux ("spider") LEDs on each board. It is designed to be operated from 12 volts DC.

The light's color temperature appears to be rather neutral; probably near 4,900K, which is a very slightly warmish shade of white.


Measures 24,100mcd at an If (drive current) of 41.9mA.
Viewing angle appears to be ~100.

LEDs International, white LED module, TB-6016
Received 02-20-07, tested 02-21-07
This is an array of three printed circuit board, each with three super-flux ("spider") LEDs on it. These LEDs have a very wide viewing angle; estimated at ~120. The LEDs on each PCB appear to be connected in series with a series resistor (one on each board); each board is connected in parallel with the next. That makes a total of 9 LEDs.
The result is that if one LED fails open, you will not lose them all; only the PCB with the faulty LED on it will go out.


Here is the module itself. It is composed of three boards with three high-flux ("spider") LEDs on each board. It is designed to be operated from 12 volts DC.

The light's color temperature appears to be fairly low; probably near 3,800K, which is a warmish, slightly yellowish shade of white.


Measures 9,600mcd at an If (drive current) of 54.1mA.
Viewing angle appears to be ~120.

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 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.
