Over the years training for endurance cycling events and measuring courses I’ve used many different light sources for night riding.
Lately I have had a need to do more measuring at night due to working more congested courses, etc. I don’t typically post endorsements for products but really needed a new lamp and bought a 1200 lumen, waterproof Bright Eyes Rechargeable Bike Headlight, Square model with 6400mAh Battery from Amazon for $49.00
The battery pack comes ready to be mounted to the bike frame and is easily swapped out with a fresh battery. The lamp mounts easily and securely to the bars and on 1200 lum I’m getting 3.5-hours of riding time per charge.Replacement packs are only $19.00 so for under $100 you can basically ride through the night if-needed. The extra packs can be swapped in under a minute.
Sadly I admit I’ve had much less success with $300 lamps. If you’re looking for a good deal on a quality lamp and need daylight at night time this lamp is worth a look.
A side note, I also use a 350 lumen helmet mounted light to assist in seeing where I point my noggin too. Makes identifying road name signs a lot easier at night in addition to the bike mounted light.
