The Pulsar II Light by Princeton Tec is an upgrade from that incandesent bulb. This Princeton Tec Headlamp is slightly larger than a quarter and weighing 7 grams, the Pulsar provides instant illumination for any situation and offers easy battery replacement. This compact Ultrabright Princeton Tec LED burns with unbelievable intensity making it the perfect choice for key chains, backpacks, book bags, zippers and emergency situations. PULSAR II Princeton Tec has taken the smallest item in our product line and made it better - with a flick of a switch*. The Pulsar II stays on so you can free up your hands for other tasks. Like its predecessor, the Pulsar II can also be illuminated merely by squeezing its compact, lightweight body.
SPECIFICATIONS of the Pulsar II Light by Princeton Tec
This tiny light is plenty for lighting up your tent. Great as a backup, and a primary in camp to preserve your headlamp. Get this light! No, get several of these: one for your pack, one for your car, one for your keychain, and some for friends. You will not regret it.
After purchasing two of these, I've switched over to one of princeton tec's water resistant lights because the batteries kept getting damp and rusting which ultimately led to dimming of the light. I did really enjoy the size and usefulness of this light.
this light is the perfect size for a keychain. i've bought several other compact lights that are just a bit too big so i don't always have them with me when i need them (frequent power outages is the developing world). this has served me well and many occasions. good light, good design.
Great gift/grab bag item. I bought several this season, as well as in the past. Everyone loved receiving them They have great utility and are lightweight on the keychain. The light they emit, is quite strong. The battery is also durable for long lighting.
A great addition to the key chain. Lightweight and durable. The LED provides more than enough light to find the door lock, an earing back even a contact lens in the dark. I've had one for a couple of years and it's still going strong.
