Mr. Williams, we just now received an update on your question and you should read this before you try what we had sent you earlier;
The XPP-5420B or G (B=Black and G= Green) has a set screw in the side of the head that has to be loosened in order to unscrew the head.The set screw has to be tightened again to conform to the standards of “Intrinsically Safe”. In addition, changing the battery should only be done outside the hazardous work area. If he got the head unscrewed, sometimes it’s hard to get the reflector to start coming out. Tap the flashlight against your palm and the movement should start the reflector to slightly come out. Then pull the reflector out and the batteries are inserted in behind the reflector. Link to the instructions http://www.baycoproducts.com/images/PDF/ProductManuals/INS-5420DL-13E.pdf
From the instruction manual:
1. Loosen the locking screw located on the side of the lens cap
