spill vs flood

OK guys(and Gals). I have been doing a little extra crawling at work lately and I have a few thoughts about Flood and spill. I have been using a Spark 125 OW lately for my primary work light. The battery died and rather than replacing I just grabbed one of my backup lights. The Streamlight Argo HP. So the Argo has a very tiny hotspot. I mean small!!!!! Smaller than any of my hand held throwers. Now the amount of spill is incredible! Way more usefull than my Spark. I think Streamlight lights use this philosiphy of small hotspot and with spill? I have a lot of access to Streamlight lights and most of their lights follow this pattern. I have been seriously considering a Zerbra for work because I want flood. I think I would belly up for one If I didn't hear that they are goning to release a newer version 502. Anyway today I'll try a some a scotch tape on the Spark today and see what happens.

spark makes diffuser lens for their ST6 series of headlamps.
its very possible they would have a ST5 diffuser lens as well. or at least in the near future.
