Whether you're headed out for an all-night excursion or need max light output for that final lap, NiteRider's Pro 600 LED is perfect. Using NiteRider's innovative D.I.Y. software, you can program this light to your needs. Want to extend the run time? No problem. Desire a custom flash mode? Just program it in. The options are virtually limitless! This smart system is powered from 4 to 48 hours by a quick-release Li-Ion battery, so no more dealing with straps every time you need to charge up. Plus, the light weighs in at a mere 99 grams and attaches to both handlebars and helmets.
NiteRider makes it simple to maximize your Pro LED light system.
Lead Acid batteries are the most common power source on inexpensive lighting systems. Lead Acids hold their charge for longer periods between use, which is a valuable feature for an occasional night rider. They also dim gradually during use so you'll have some light even if the battery is fading. The primary drawback is about twice the weight of the better batteries for the same capacity. Also, they typically last between 200 and 400 charging cycles, whereas superior models will last through 300 to 2,000 cycles. Lead Acid batteries will also lose more of their capacity in cold weather than the better ones.
Ni-Cads are popular because they're moderately priced, lighter and smaller than Lead Acids, less affected by weather, and are safely charged with simple chargers. A common misconception concerning Ni-Cad batteries, is a problem with "memory." You may have heard that you need to fully drain a Ni-Cad battery otherwise it will remember where you began charging it and only retain that much capacity. This has never been proven in consumer batteries or cycling lighting systems.
NiMH batteries are significantly lighter, and even smaller than Ni-Cads meaning that they can provide longer run times without excess bulk. NiMH batteries, however, must be charged correctly. Whereas Ni-Cad batteries can handle continuous charging with relatively little effect, NiMH batteries can be damaged by overcharging. This is why NiMH powered lighting systems typically include "smart" chargers that protect the battery.
Li-Ion batteries are the newest, and already among the most popular type found in consumer electronics because they boast one of the best energy-to-weight ratios, low maintenance, and no memory effect. Even better, they offer a higher power density, which means longer run times from a super-light battery (Lithium is the lightest of all metals). Another great advantage is that Li-ion batteries cannot be overcharged. Plus, they lose only 5% of their charge a month, so they're ready to go when you (or your buddies) are. A drawback of Li-ion batteries is a fixed life cycle, independent of the number of charge/discharge cycles. This means that a 3-year-old Li-ion will have less run-time when fully charged than a new Li-ion battery that's fully charged. Also, as a new technology, Li-ion batteries often command a higher price.

I reviewed this previously but apparently my review didn't fit with the proprieters desire to artificially inflate the price. Do your homework and check prices before buying this! It is not a bargain at this price. A light with twice the power output can be purchased at this price just about anywhere...just go to Google and look. Jax - if you have any credibility you will not censor this again. It is unfair for mountain bikers not to have access to information. I for one will look out for my fellow riders...will you?
This light was obsolete in 2010. It can be purchased just about anywhere (if inventory remains) for about $200. I would hate for somebody to buy this light thinking it was the latest and greatest. You can purchase the NiteRider Pro 2200 Dual Beam for less than this outdated tech. Hopefully this is just the wrong light that is being priced as a "closeout"
