That's right.
The E2/E2e MN03 60Lu/75min Lamp Assembly looks like this:
Please Note:
Shown is the MN01 Lamp Assembly identified by the assembly's Black colour.
The MN03 assembly is a tan/brown colour.
The P61 120Lu/20min Lamp Assembly for the likes of the M2 etc looks like this:
Please Note:
Shown is the P60 identified by "P60" on the Blue label.
The P61 can be identified by "P61" on a Purple label.
You'd think it would be vital for SureFire to have a photo of the right lamp assembly next to the right part number and information since making a mistake is likely to blow the bulb.
Anyway, you get the idea? The P61 will not fit in the E2e.
