I have been looking for a new flash light and found this one on eBay and ordered it a couple days ago. Its an UltraFire WF-501B i had to order special batteries and a charger for it but when i got it last night it was well worth it. It is crazy bright and has multiple setting. I paid $25 total for everything shipped.
I read the specs on it. If its a true 900 lumen light, you better buy batteries in bulk. If it uses the surefire batteries, I buy them on ebay by the box. Just search for them on a buy it now price that is the cheapest with free shipping. I carry a Fenix Pd30 daily and go thru 2 batteries in about a month. You never realize how much you need and will use a light till you start carrying one daily
I thought they make rechargeable batteries for that one?
Ya i bought 4 X UltraFire 18650 3000mAh Rechargeable Li-ion Battery 3.7V and a charger. I dont think its actually 900 lumen but its the brightest lite i have ever used. It lights up the top of 75-100ft tree with no problem.
