Review in Progress


Bronte X20...


Thanks to Bryan at Shiningveam for providing the X20 for review.

I’ll be reviewing the X20 in two sections: first, I’ll discuss the light objectively (the facts about the light itself), then I’ll discuss the light subjectively (my impressions about the light's performance when used for specific applications). This is a long, powerful light geared for maximum throw, and Bronte advertises it as being useful for outdoor and tactical situations, so I'll be reviewing it as such. If you have any other specific applications you'd like the light tested for, let me know and I'll see what I can do.

Spectral Analysis

All light that we see as white is actually made up of several different colors put together. The relative intensities of the different colors in the mix are what determine the tint of the white we see. For example, cool white LED's have a lot of blue, and warm white LED's have more red or yellow. This measurement was done on a home made spectrometer. Note: the peak in the 900nm region doesn't really exist, it's a piece of the second-order spectrum that's showing up here because of the high intensity of the light source.



Output, Current Draw and Runtime



Note: ANSI runtime ratings are the time it takes for a light to fall to 10% of it's original output. Also note that my measurement for the run time on low is a calculation based on the current I measured and the used capacity of the batteries.

Note: The vertical axis of the graph below represents a relative brightness measurement using a home made light box. The horizontal axis is time in hours:minutes:seconds. Runtimes are stated in hours:minutes:seconds. These graphs may be truncated to show detail.

Long Term Impressions


I'll fill this part in after carrying the light for a while. If nothing get's added here, either I find nothing else worth noting about the light, or I end up not using it often.
