Current LED Selection

A little confused by all the LED options or giving the Alpha as a gift?

I suggest my "Maker's Choice" : MC18-B (Neutral White) 4500K.

Color Temperature:

Color temperature is a measure of visible light that relates to how "warm" or "cold" the light appears.For me, good color rendition is incredibly important and one thing that sets my lights apart from many other name brand flashlights and virtually all off-brand lights.

Color temperature is measured in "degrees Kelvin." A clear noon-day sky is considered to be 6500K (cool white) and traditional 100W incandescent bulb is about 2870K (warm white).

"Neutral" tint is between 4000K and 5000K. Many flashlight enthusiasts prefer a neutral tint for it's balanced color characteristics, but the warmer the color of the LED the lower the maximum brightness.


Comparing the Alpha Series Options:

In the chart below I divided the Alpha series "low power" and "high power" categories. Keep in mind that "low power" is still brighter than 95% of the flashlights you can buy in any store.

The main difference between the two categories is the LED driver board. High Power lights deliver 2.8A of current to the LED and the Low Power lights deliver 1.4A. This should "basically" mean twice the run time for Low Power lights, and much less heat when operated on full power.


What's in a name?

The Alpha is currently divided into 4 variants. Each one has an alpha-numeric designation so you can tell them apart.

The first two letters tell you what type of LED the light uses. RIght now that could be an MCE, XML, XPG, or XRE.

The next two numbers tell you what type of battery. Currently all lights use 18650 size batteries. If I ever make a light that uses AA batteries then the designtation might be something like MCAA-B.

The letter after the dash indicates the type of lens or optic used. Right now all Alpha lights use the Ledil BoomSS reflector, hence the designation -B.

I do have a very limited number of TIR (Total Internal Reflection) optics available for XML based lights. Contact me if you are interested. The TIR optic produces a more intense hotspot and correspondingly less spill.
