First, welcome to BLF! Search, read up, and learn.
Maglite 4D non-LED is rated 72 lumens and probably looks darn close to the 2D incandescent in my old beamshots thread (you can compare with others there). With that TR-J18, I hope you've studied up on Lithium Ions and understand the dangers of Lithium Ions in series and proper care for them with a DMM. If not, read up immediately.
Don't get caught up in looking for more lumens. You can have a light that throws further and puts out far less lumens versus a light which puts out a ton of lumens and hardly throws at all. You have to look at beam profile and what kind of area you want to light up. I own a 1 acre lot and can get by scanning the lot with a 150 to 250 lumen thrower (spot beam) or I can use a 800+ lumen XM-L "flooder" and light up most of the backyard (although it's tough to see stuff in the distance when you are lighting up everything in front of you. My fake Solarforce L2 with Manafont Ultrafire 3 mode XM-L drop-in or my KD-C8 XM-L is plenty enough to search my yard. The L2 compared with the KD-C8 can be compared in this beamshot thread.
