I like the LED for both applications, its a clearer, brighter, whiter light. IMHO more blinding in self defense situations. Drop in LED upgrades for the g2 are all over ebay for around 15-20 bucks and worth every penny. They are advertised as producing 300+ lumens I dont know if I believe that or not, but still brighter than the stock yellow xenon bulb, not to mention 10x the battery life! I mounted a g2 on my HD 12 Mossberg 590 with a pressure switch and a 270 lumens cree bulb...works great. I put many rounds thru it at the range to make sure it would hold up before I trusted it for HD use, and I've had no issues yet.
