I bought a Pelican Super Sabrelite last year, and wanted to purchase a spare xenon bulb, only to discover that it's extremely difficult to find, and expensive too, I only managed to locate it at a scuba diving store, and was available if i placed an order and wait 2 weeks for delivery costing $AUD40~$30USD.
The SL 4AA Lux has solve all the need to carry a spare bulb, is bright, water resistant and meet all my needs, since i don't go scuba diving anyway. Although the xenon light bulb has good throw and appears to have a lot of light initially, it quickly diminishes over a short use. The luxeon bulb makes the subject look alot whiter, with less ability to differentiate colour from a distance. However, it is absolutely amazing with the constant regulated output, and superb with run time. I will definately vote this as flashlight of the year!
