Trust me on this. Once you switch to 18650 battery powered light, you will never go back. I have used and still own several expensive lights and this is what I use at work.
Convoy S3. Insanely bright, really good runtime with the 18650 batteries, T4-7C LED is warm tint(not blue like cheap LED flashlights), High is about 600-700 lumens(It really is, not the typical overstatement) but does get hot on high, so only use on high for 5 minutes or less. Medium is about 300 lumens and is perfect for most work. Medium will give you 3+ hours of runtime. The output is also regulated meaning it will maintain its high output while the batteries drain. The beam profile is wide and floody which is better for us with the close up work we do.

Here is the battery charger you will need. This one comes with a car charger, If you don't need that too, they have one without the car charger for a couple of bucks less.

The total will be about $58. If you are looking for a great set up, this is a good one without breaking the bank. The whole kit will cost about the same as a Fenix PD32 or EagleTac(less actually) light and perform as well. I have several "high end" lights too (EagleTAC, Fenix, Olight, Nightcore and Jetbeams) and this is what I use at work every day. I used to use Fenix P series lights at work all the way back to the P3D. You don't mind abusing this light because it is only $22.
