The Mini-Lamp Zoom

Mini-Lamp Zoom Design


If you need a small lightweight torch to throw a very narrow beam of light as far as possible then forget all about watts and lumens.  The most important factors are the type of LED and Lens or reflector which are used, and how they are set up.

The inverse square law determines that to make a beam of light throw 3 times as far, it needs 9 times the amount of light (lumens).  To get 9 times the lumens, the available LED’s don’t have the correct characteristics needed for throwing the light forwards and for being manipulated by a lens.  They would also create far too much heat.  What’s needed is the most intense light coming from the smallest surface area, which also projects its light forwards in the tightest possible angle.   

This LED is the Cree XR-E EZ900 R2.  If this LED is used correctly with a good quality Aspherical Lens the beam of light will be pencil thin with virtually no Spill or Corona, just a concentrated hot spot.

“Think of using a hose pipe, you squeeze the end of the pipe to get the water to shoot a greater distance, not turn the tap up higher.”

About the torch

Using a Cree XR-E LED (R2 bin with the smaller EZ900 die) and a well set up high quality 39mm Aspherical lens, it creates the tightest possible beam pattern.
Due to the concentration of the light beam, and the amount of light the high quality lens set up captures the torch will throw its light 350 metres.
Left on full power continuously, the 18650 battery will last over two hours.
The focusing mechanism is a simple one handed light pull and push operation, this offers a spread beam or highly focused beam with virtually no spill and great throw.
