I plan on buying a Tec 40 from a local ****s Sporting Goods and was wondering what bulb can I use with alkaline batteries that will give me a really bright light. Ive read about people putting in other bulbs but they all use NiMH batteries. I also have a Surge and just bought 50 AA's on ebay. I dont want to spend $40-$50 for 12 or more rechargeable batteries and a charger at this moment. I did all kinds of searches but everyone here uses NiMH's. Thanks.
