General Hybrid UK Luxeon Driver, retail ($Unknown/TBA) (
Manufactured by General Hybrid UK (
Last updated 07-20-04

The General Hybrid UK Luxeon Driver is a small, potted circuit that operates on any source of power up to about 3 volts DC, and delivers 350mA to a 1.2 watt Luxeon Star LED.

It is small enough to place inside flashlights, portable luminaires, and other portable lighting fixtures, and runs from 1.8 to 3.0 volts DC from two D, C, AA or AAA cells; one lithium CR2 or CR123A cell; or a 3VDC "wall wart" that can deliver at least 700mA.

It operates at 1.4MHz, so LED flicker will not be an issue here.

 SIZE (Compared to a CR123A cell)

To use the General Hybrid UK Luxeon Driver, connect the last pin and the center pin (pins 3 and 5 on the version I'm testing) to any source of DC from 1.8 volts to 3.0 volts; positive (+) on the last pin, and negative (-) on the center pin. If you wish to use an on/off switch, you'll need to supply and connect it yourself. It's probably not a very good idea to connect power to the driver circuit without the Luxeon LED connected, so please don't energise the driver circuit just yet. The circuit has open circuit and short circuit protection, so it probably wouldn't hurt it to power it up without a Luxeon LED attached - but it's never a good idea in any case.

Connect a 1.2 watt Luxeon Star LED to the first two pins of the driver circuit: positive (+) to pin 1, and negative (-) to pin 2.

If your circuit has a SD ("Shutdown") pin at position 4, connect it to the positive (+) terminal to turn the driver circuit on, and connect it to the negative (-) terminal to turn the driver circuit off.
A SPDT (single pole, double throw) switch ought to do the trick here.

Since this product uses any source of 1.8 to 3.0 volts DC you can find that can supply at least 700mA, this section will be skipped.

Current usage measures 670mA on my DMM's 2A scale, using an almost-new CR123A 3 volt lithium cell.

Since this is a circuit meant to be installed in something and then not screwed with, I won't throw it, try to drown it in the loo, kick it, smack it against a steel rod, stomp on it, or otherwise abuse it like I might abuse a regular flashlight for the sake of this website. So this section of the web page will seem more bare than this section of the web page on a page about a flashlight.

This circuit is small, so it will fit into flashlight cases, luminaires, and other portable fixtures that can be operated on 3 volts DC, from batteries or from a "wall wart" type AC adapter (that outputs no more than 3VDC) that can supply at least 700mA.

Here's a photograph of one of the evaluation boards I was sent.
As you can see, the pinout of this circuit is as follows:

1: LED anode (+)
2: LED cathode (-)
3: Vcc (1.8 to 3.0 volts input) negative (-)
4: Shutdown
5: Vcc (1.8 to 3.0 volts input) positive (+)

This pinout and the connection instructions above are with the flat portion of the circuit facing you.
The evaluation board is equipped with female banana jacks for all connections.

Test units were sent by P.B. of General Hybrid UK, and were received on 06-18-04.
I apologise for the delay in getting this device on my website; I had to find and purchase test leads terminated in male banana plugs and then cut the test probe ends off and then buy and connect a pair of wires terminated in spring-loaded mini hooks for the Luxeon LED before I could use the GH circuits and the evaluation boards that were included with them.

Since this is not a flashlight or other thing that glows, I cannot assign a "star" rating to it.
