Product Details


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 effi ciency and brightness of Ultrabright LEDs.


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.


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.


Princeton Tec’s advertised product weights always include batteries. For many products, battery weight is a large percentage of overall weight. Weight can be significantly reduced by using lithium batteries in lithium-compatible products.
