I thought long and hard about all the horror stories with battery's when I bought my new light.... took it in for the 1st time yesterday.

I bit the bullet and bought a 21w Salvo with the 10.4 Li-Ion... and I tell you, its stunning... spot beam, the Havoc has a smaller head than the Rebel as the ballast is in the battery canister. I figured that if I bought Li-Ion I could have a few future options.... either go for an LED head to boost the burn time, or if I wasn't happy go with a bigger head.

As it happens is got to be the brightest torch I've used... i'm really really impressed... we'll see how we go.
