Wow, the Edison 10! We opened the UPS package with anticipation of playing with something that was over the top, something really nice that we normally couldn't afford, or justify. It's much like a Seven bike or a Chris King hubset.

First impression when opening the box is this is a minimalist system. Minimalist packaging and manual and charger/battery/light. The handlebar mount is a very elegant rubber band and there's no helmet mount included. This system is all-meat no side dishes.

Now for the meat. The light head is the best constructed of any we've seen. It is elegant and bulletproof. The charger is a little computer with a digital readout. It thinks a lot and it tells you in english what it's doing. We hear it's completely programmable too. The battery is waterbottle-size but it's soft and fairly light. There's a small lithium-ion battery in there that will crush the energizer bunny.

The included handlebar mount is simplistic but it seems up to the task. It is a far cry however from the center-mounted, fully adjustable systems from Niterider for example.

Performance: When you see the beam pattern and realize the run-time, you quickly understand why this is the best. The beam is white, consistent, non-flickering, and very wide. At 16 watts HID, it is the brightest available. The run time at the brightest setting is claimed to be 5 hours but since this system is so overbuilt We observed run times of over 6 hours at 3 different times.

One thing interesting is that the light is so wide and bright that a lone handlebar mount was very ideal. My normal preference of having a bar and helmet light combo or helmet only is challenged by this setup. There is so much light and it's so wide that there's no need to add a helmet light. I can see the trail and I can see where I'm turning.

I'll cut to the chase and say that it is the best light available today. The $900 price however is a problem. It's not just a problem because it's a lot of coin but because it doesn't offer good value. It is not twice as good as it's competitors as it's price would require. In the world of high-end however, price/value justification is not the name of the game. This is for the person who can afford the finer things in life or for the endurance racer who needs the best.

Metal Halide (Xenon) beam: Edison works with all Lupine rechargeable batteries (7.2 V). Its performance of 900 lumen output (in comparison: NightMare Pro 25W HP bulb has 550 lumen output) equals a 65 Watt HP halogen bulb - with the bright white light (colour temperature 6000 K) of xenon car head lamps. Beam divergence is 18�: therefore, Edison has an extremely large light range with excellent peripheral illumination.

Edison has two beam settings to reduce power consumption. Beam settings are regulated via PCS V4.1 switch unit which is equipped with a programmable capacity control.

The Edison is small in size and comes with the typical Lupine casing. Diametre: 41mm, Length: 50mm.
