Product Description Item No.   10099728

The Princeton Tec Byte Headlamp is proof positive that the smart kids at Princeton Tech think big by thinking small. Don't be fooled by the size of this Princeton Tec headlamp. Although smaller and lighter than its big brothers Fuel and Remix, the Byte is capable of packing a powerful punch thanks to a Maxbright LED. The Princeton Tec lamp comes in the form of a red Ultrabright LED to ensure your night vision will never be compromised. As with the rest of The Family, Byte is equipped with an asymmetrical single arm bracket, easily accessible battery door enclosure, and large push button switch, all at a mere 64 grams.

FEATURES of the Tec Byte Headlamp by Princeton Tec

  • Focused Narrow Beams: This pattern creates a long, powerful beam of light excellent for illuminating distant areas. The resulting long-throw spotlight is especially well-suited for night hiking and search and rescue.
  • Lumen 35: The light output of Princeton Tec lights is measured in lumens. A lumen is unit derived by the International System of Units (SI) for measuring light output.
  • Maxbright LED: The highest quality LED available from Lumileds, Princeton Tec’s 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.
  • Waterproof - Level 1: Level 1 is assigned to lights that offer a degree of water protection equivalent to IPX4 in the International Electrotechnical Commission (IEC) standards. Lights rated at Level 1 are designed for water resistance to splashing and quick dunkings. If a light with a Level 1 rating is accidentally submerged for a longer period of time, the batteries should be removed and the cabinets should be carefully inspected for signs of battery leakage. If water has entered the housing, the light should be dried and batteries replaced.
  • Ultrabright LED: The highest quality LED available, the Ultrabright LED is bright and efficient. The smooth, white, wide-beam light emitted by Ultrabright LEDs is ideal for close to mid-range tasks. Ultrabright LEDs are usually grouped together to offer a more powerful light source. Advances currently underway will continue to improve the efficiency and brightness of Ultrabright LEDs.
  • Ideal Uses: Camping, climbing and running.

Rated 2 out of 5 by from Great...At First When the Princeton Tec Byte Headlamp arrived, it proved to be very light and efficient. Very little wobble when walking and compact enough to fit anywhere.,,The downside showed when the batteries got low. Using lithium AAA's, the beam is bright when the batteries are new. As soon as the batteries start to die (in my opinion, quite prematurely), the lamp starts to flicker and won't allow you to shut it off. This renders the lamp worthless. Haven't used the Byte since experiencing the flicker. Can't predict when the batteries start running low and don't want to rely on a product that is rendered useless when they do.

Rated 3 out of 5 by from Second version improved My first one (2011) died quite quickly, and had the flickering issue when the battery was lowish - which didn't take very long at all! ,,The replacement seems to be much better, as reviews indicated. Battery lasts longer and no flicker. Durability remains to be seen.,,Very light and small for people who don't use a torch often (I rely on night vision) but need one for emergencies. Comfortable, adjustable, and the red beam saves power and night vision. Brightest setting is more than enough for me. ,,2 batteries is much better than 3 for charging. This and weight are the main pros in my opinion.,,Small problem is that it isn't so obvious which way to put the batteries in, especially in the dark.

Rated 5 out of 5 by from Way better than expected I got this light as a low budget headlamp, and because it is one of the few torches that use an even number of batteries. ,,The light is way brighter and better focused than I had expected. In comparison to the 100 lumen light of the same company. This light is just as bright up close and throws almost as far. I was so pleased with it, I purchased 7 more of these lights for the summer camp that I work at. Deff a great purchase and worth way more than the price

Rated 5 out of 5 by from Lightweight & Bright I love this headlamp! It is bright and lightweight. The only downfall is that because it doesn't have a top strap, it is difficult to wear on a helmet without slipping off. If you are looking for a solid head lamp for hiking or backpacking and weight is an issue, this is a great option.

Rated 1 out of 5 by from Don't buy this one. I wasted my money on this lamp. I'd say I thoroughly tested it, but that would be a lie.. b/c it died on the 2nd use. Completely burned out, no hope of repair. Oh well, now I know why I've stuck w/Black Diamond and other brands for so many years.
