For the last several weeks, I’ve had the chance to demo the Heser LED backup light. I’ve been very interested in the concept of LED lights, but have been largely disappointed with the lack of brightness and focus. I had read some encouraging testimonials about the Heser and decided to contact the company to inquire. (http://www.heser-backup.de/index_en.html)
The Heser unit is a bit larger and heavier than a scout, and very solidly built. These units are very well constructed and have excellent fit and finish inside and out. The inner heat sink sleeve is an impressive system. The reflective unit is a sturdy piece of hardware.
I did the recommended burn test with a unit, which was for 6 hours in a water bath. The light burned for seemingly the same intensity for the entire duration. After this burn test, I used the light for another 2 hours under water, and it’s still burning bright.
As with most LEDs, the light is a nice white, making normal 3C lights looks yellow and dull in comparison. I was impressed with the Heser’s ability to project a focused beam. It is not quite as tight as a scout, but darn close and certainly tight enough to use for signaling in any of the conditions that a scout can. In addition, the Heser puts out enough light to use as a primary at night.
In summary, I was totally impressed with these lights. The only downside I can see is the price. Originally, my intent was to carry these for resale, but I’ve sadly had to conclude that few if any of my customers would be willing to part with enough cash to cover my considerable costs on these units and turn a profit. That’s really the only negative point I can muster.
If I were diving caves, I'd have two of these on my chest without question.
