Customer Reviews

excellent for all your lighting needs
The best LED key chain light I have owned. The Princeton Tec Impulse offers 3 different light intensities among other options and is easy to turn on and off. The only problem is that the clip open a little too easily. I lost mine after 6 to 12 months so I tried the Princeton Tec Pulsar which is inferior to this product by far. If I ever buy another LED key chain light, it'll be the Prince Tec Impulse.

Capable light
I purchased this light to replace an older one whose batteries would have cost me about half the price of this one. The older one had a difficult and temperamental switch, and was very user friendly. This one has a nice switch that works well, and is multifunctional. It has a snap ring so I can easily remove it from my keyring.

Really, no down side. I plan to purchase two more with the white light (the one I purchased is red for maintaining my night vision).
