In my case, the Radbot 1000 kept turning itself off, so there was no light, bright or otherwise. But the battery life was great as a result
I have a Radbot 1000, and I was disappointed when I did the math -- on steady mode it claims a 15hr runtime, and even using 1200mah primaries, it only puts about 1/5W into a 1W LED.
On that note,
BrianMc did some measurements with the Radbot 1000 and his assessment is found here:

So if you run the Radbots in steady-on with NiMH cells, the cells need to be swapped out every 2 hours to stay at or above 75% of max output with NiMH. In flash mode, a 3 hour changeout will stay at or above 80% of maximum.
I speculate the 1W blinkies on the market only deliver 1W in flashing mode, if even then. If you want a high-brightness steady-burn light, the Hotshot might be your ticket to ride. I haven't checked burn time in steady mode, but if it's of particular interest I could do a runtime test.
Another steady-burn monster is the DealExtreme SKU 20333, a flashlight with a red emitter:

Might be a good "early warning system" for people who ride in dense fog, although flashing would still be better yet.
