This light is tough, waterproof and highly effective, with enough runtime that you won't get caught out even on longer night-time rides.
So far as I can tell, this is a rebadged version of the RSP Asteri 3 that Big Dave tested back in March. He gave it the thumbs up and who am I to argue with a man who has been through more lights than Blackpool Illuminations?
RSP’s Micro Flexilite front is a versatile LED that is remarkably proficient beam relative to its size, so it's perfect for clutter-free Audax, tourers and extended playtimes on the best bike(s). Weather seals are top-notch and burn times are broadly on par with the competition, although the tiny screws mean batteries are best replaced from the comfort of home, rather than by road or trailside.
Don’t be fooled by their cutesy looks, NiteRider’s Lightning Bug 3.0 and Stinger set are very competent LED lights with great output and around 100hrs of life from a set of watch-type batteries.
