NEW BULB FOR THE BOREALIS FLASHLIGHT
750 LUMENS FOR 75 MINUTES

As you may know the Borealis 1050 lumens flashlight is the most powerful military/police flashlight in use today.
The Borealis will make 1050 lumens for 50 minutes on rechargeable batteries. Now a new bulb is available which will run the light for 75 minutes with a drop of only 300 lumens.

Lights in use by police today are the Magcharger, the Stingers, the SL 20 up to 200 lumens, the Ultra Stinger-295 lumens, the Pelican 7060-135 lumens, and the Fenix TK series up to 240 lumens.

Military forces use a variety of Surefires as weapon lights with 120 lumens and hand held like the Surefire M-4, 350 lumens and the Surefire M-6 at 500 lumens.

So, the above statement of the Borealis been the most powerful is not an exaggeration, many are been used daily by police and many are doing tour of duty in Afghanistan and Iraq.

What the new bulb does is extend the run time to 75 minutes without reducing drastically the output.

As no other duty flashlight with the same lumens is available, I decided to conduct a shoot out against a big two million candlepower spotlight, the one at hand was an almost new Brikmann Q beam Max million II (two million candlepower) with a reflector of five inches wide and a big bulb of 75 watt.
All this in competition to a bean sized 30 watt bulb and two inch reflector of the Borealis.

FIVE INCH VERSUS TWO INCH




This particular Borealis has a Light Stippled reflector, a reflector designed to give a good balance between flood and throw, but given the semi custom character of the Borealis three other reflectors are available, smooth for maximum throw, orange peel for just a little less throw but more flood (also called side spill) and a medium stippled reflector designed for a big flood but with the range limited to 100 yards.

As the night was bitterly cold I decided to take the pictures and shoot the beams right out of my second story kitchen window, with the short tripod legs resting in the kitchen sink.
The target is the white and blue cabana which is the second building in the picture after the fence.

The target is 74 yards from my window, with back trees as much as 85 yards (they are still visible with both lights).

Due to the big reflector in the spot light, the beam is concentrated in the center of the picture and illumination from the side spill is not as great as it is with the Borealis 750 lumens bulb.

Observe both pictures and you will see more area illuminated by the Borealis 750 lumens bulb, than is illuminated by the two million candlepower spotlight.
Still the intensity of both beams is similar at the center of the target area.

Q-BEAM MAX TWO MILLION



BOREALIS 750 LUMENS 75 MINUTES BULB




In conclusion the new Borealis bulb of 750 lumens is worthy for those that will want a run time of 75 minutes. Even after loosing 300 lumens the Borealis still is the most powerful flashlight used by the police and the military.

The light can be ordered with the 1050 lumens bulb installed and the spare as the 750 lumens or vice-versa. You can also order the reflector most appropriate for you work, the only light in the Industry that offers you a choice of four reflectors.

Cheers.
