I have the new version TL-2 LED that I've done a side-by-side comparison with the original version TL-2, a Pel M6 LED, and earlier this evening compared it to an Inova T3. The new version TL-2 EASILY out-throws the original version and the hotspot and sidespill are both noticably brighter. It out-throws the Pel M6 LED as well; not by as wide a margin as the original TL-2, but by a noticable amount none-the-less. Sidespill brightness between the new TL-2 and Pel M6 LED are pretty close, but the hotspot brightness nod definitely goes to the TL-2. When compared to the Inova T3, the throw is pretty close...in fact, too close to give a nod either way. But in just "how much" of an area the two light up at a distance of 200 feet, the T3 wins hands down. This was a pretty unfair comparison since it was a LuxI (TL-2) against a LuxIII (T3). I only did the comparison for throw purposes...
The main reason for the increase in head size of the new TL-2 is because it has a much deeper reflector than the original version. They both use a HD LuxI. The regulation circuitry used in the new version accounts for very little of the larger head.
All in all, I think the new version TL-2 LED is well worth plunking down some of your hard-earned $$ on!
