A good recommendation. I've got several of the PDW Danger Zone, which has two 1/2 watt LED's instead of the Radbot's single 1 watter. All of them are very bright and highly visible. A possible side benefit is that they use the same mounting brackets as the Planet Bike Superflash, which I already had, so all my bikes and lights are interchangeable.
I do find the PDW burns through batteries faster than the Planet Bike lights, so I've taken to using rechargeables and swapping them out for fresh ones every couple of rides.
