Power meets versatility in the Torrent LED. Itfs small enough to be a backup light, but with a 500 Lumen Maxbright LED, Torrent is more than powerful enough to be a main source. Dive lights are not just for night diving, and the Torrent LED is Princeton Tecfs favorite dive light for looking into caves/crevices, restoring lost colors at depth, and daytime wreck diving. For those who need a great backup, an efficient main source, or just all-around great dive light, the Torrent LED is all of the above. Focused narrow beam: This pattern creates a long, powerful beam of light excellent for illuminating distant areas, or for use during fast paced activities. Maxbright LED: The highest quality LED available. Princeton Tecfs Maxbright LED is extremely bright and efficient. This single LED emits a smooth, powerful, white light useful for a wide range of tasks. Princeton Tec uses collimators or reflectors with the Maxbright LED depending upon the application. Regulated LED: Lights that feature regulated LEDs have a sophisticated regulating circuit that maintains initial brightness as long as the batteries have sufficient voltage. They are so sophisticated that if they had eyes, they would definitely wear a monocle. Traditional lights are very bright initially, but immediately begin to dim and continue to dim until the batteries are drained. Constant Brightness is a term used to describe products that have regulated LEDs. Underwriters Laboratories Inc. (UL): An
