Grease, check out the HL series Streamlights if you want room clearing light pattern. The HPL will give you not quite as wide a beam but it will shine a LOT farther. I had a TLR1 HPL and got rid of it because it didn't give me as wide a beam as I wanted for building use. The TLR1 HP makes me happy.

Here is a link to their beam patterns.

Oh and I didn't derail this thread, I DID talk about a weapons light I sold.
