Serfas True Road Bicycle Headlight Review

I have been using the Serfas True 250 for several years but replacement batteries have become too expensive. Battery life lasts much longer when I use medium settings and slow flash throughout the day. So far about ten days of skiing or 10 to 12 hours. However, I don't like the strength of the continuous light, it seems weaker than my old True 250. Even high settings appear weaker.
