The Surefire Stiletto Pro is an amazing product.
I only have one gripe with it. I really, really really wish for peace of mind that I could replace the battery myself. I don't like the fact that the light has a finite life far short of what the LED diode is rated for.
I am actually using the Stiletto Pro on duty. It lacks sufficient candela to pierce past most photonic barriers and into cars but for general searching and tasks, its an amazing light.
The Cloud Defensive second generation heads are easily outclassing almost everyone else. I really, really, REALLY like what they're doing. I have no experience with their multi mode heads with the single output HC head is really, really nice for throwing light and the tone of the light itself is wonderful. Its not too white or harsh and its not to yellow where its not providing sufficient contrast.
