LED Headlamp with Exclusive Batteries. Designed to Perform. 3 Modes, 1800 Lumens, Telescopic Zoom, Adjustable Strap. Perfect for Camping, Hiking, Working. Rechargeable Batteries and Chargers. ALL BATTERIES ARE THE SAME? WRONG! First time and experienced headlamp buyers often can make the same mistake. You look to buy the highest lumens for the cheapest price. The mistake is that the batteries in these headlamps minimize performance. Top-notch batteries make a stunning difference in brightness, intensity and duration, but they cost more money. In fact, if you would buy M1 batteries individually you would pay $20-$25 /pair. The competitors' batteries retail for $5-$8 /pair. WHY SETTLE FOR A FEW FEET WHEN YOU CAN HAVE A FEW HUNDRED. If you need a directional light source for work indoors or work in close quarters - no worries the M1 has a low beam setting, BUT LET'S BE REAL who wants to be limited to the indoors? Zoomed in on HIGH BEAM the ultra bright modern square M1 headlamp LED has a range of up to 300 feet. Serious throw WAAAY OUT THERE. DON'T BE FOOLED. YOU'RE SMARTER THAN THAT. 2000, 30006000 LUMENS ?!. What some products don't tell you is that the advertised lumens are the maximum output for the Light Emitting Diode (LED), not the actual light output that you experience. The M1 has a Maximum LED Output of 1800 Lumens, but we conservatively rate at 800 Lumens of light output. IT'S REALLY BRIGHT! TELESCOPIC ZOOMNO, REALLY. TELESCOPIC ZOOM. You want a headlamp because you want your hands to be free. Whatever the activity - we do it all. Some headlamps don't zoom, some need two hands to 'hold' and 'pull' to zoom, but the M1 is telescopic. So if you need one hand to manage your equipment, the other hand can rotate the bezel of the headlamp to zoom in or zoom out. The M1 Aluminum head measures 1-3/4 inch long and 1-1/2 inch in diameter. THE PACK UP AND GO-GO-GO GUARANTEE. Don't worry. We know that you work hard for your money. We do, too. We'll make you a deal. Put the M1 in your cart right now. Buy it. Use it.
