Smudge’s backup is ace, but at the end of the day it’s a decent light but at the price, you could get a fantastic light. It’s noticably better than the dealextreme XML light but then, it’s a bit crap frankly.
I won’t recommend a specific model since there’s probably newer, hotter lights, but the MJ-872 I use is sub-£100 and kicks the bejeesus out of these. Mine came with a sealed battery and quality UK charger as well. It’s the first light I used that I thought “this is enough”, and it still outperforms some very expensive lights. There’s other very similiar lights, and some newer ones that might well be better.
