I highly recommend this product after comparing it with the Solaris which I also have.
4 Leds (very bright)
Bright main xenon light.
No weaknesses that I have seen. I use this lamp when I go night skiing. If the slope is sufficiently lit, I use the Leds and otherwise the main beam. I use the Solaris if it is really dark or when my batteries are low. The Solaris is a good backup light in this case.
Definite Buy. Value for money.
