The performance is greatly improved: - Designed to last 20 years instead of 15 - 150 lumens instead of 35 - Reach 265 m instead of 55 m - 3m may drop instead of 2 However, the scope increase is at the expense of the light distribution: the beam is focused on a diameter too small for my taste More annoying, you can not use rechargeable batteries, light loss is prohibitive To see with the battery life, not suitable for the new model
