Yeah I’ve got a holy Moses, standard white LED, medium lens. It’s hard to know what a 2500 lumens should be like, but it’s certainly a lot brighter than my Hope R4’s, which are a 1000 lumen, but I was expecting them to be a bit brighter. Maybe a narrow lens would have been better to go with my hope headlight. Having said that it’s still plenty of light. I went for the QR 5200 battery. Everything’s really well made although the bar attachment could be better
