I have a Magicshine 900L. For the price, it's a very bright light. The quality is so-so, and if you do some web reading, you'll find stories of problems with this light. My wife uses the Magicshine 900L on her bike and it has worked fine for the last two years, with ocassional use. I also bought her a Magicshine taillight, which is also inexpensive and bright. The first one we received failed after a few weeks, and the good people at Geoman Gear promptly replaced it with a new one which has been working for about a year now.

The original battery for the 900L was recalled by the US Distributor, Geoman Gear. The original battery was a piece of S*!t. the replacement battery I got from Geoman Gear looks like a well engineered and well built battery. The connectors on the new battery are compatible with my existing 900L light and taillight.

I bike commute to/from work 5 day/week, year round, so bright, dependable, long-lasting lights are important to me. Therefore I run a Dinotte headlight, Dinotte taillight, and in the summer months a Dinotte daytime running light. Dinotte lights are very high quality but also very expensive. VERY expensive, especially compared to the Magicshine lights. But reliability and longevity are paramount to me, so I am willing to spend the extra cash. All my Dinotte lights are three years old and after almost daily use, they are going strong with ZERO problems.
