The Flea 2.0 USB combo is a great way to invest in Blackburn's ultra light, rechargeable front and rear lights at a savings. The Flea front light uses four super-bright White Nichia LED's to achieve a 40 lumen output at 17 grams total weight. A USB rechargeable battery produces 3-5 hours of run time. The Blackburn Flea rear light has 4 ultra bright red LED for night riding safety. The Flea rear light comes with a Velcro strap and a belt clip making it easy to mount almost anywhere.
Only one USB charger comes with this combo pack, other than that this is a great product. Its a lot of light in a very small and light package, and the new USB chargers work very well. I like to cycle to work early in the morning, and use two of these on the drop bars, and a red Blackburn flasher on my seatpack; I can make the 20 mile ride to and from work all week on one charge.
Blackburn Fleas are a failed product. 50% are defective out of the box. The ones that do work out of box fail quickly on the bike. Unreliable. The charger can fry the circuits. Dont waste your money on this beta product.
