One of them fits the 4, 5 and 6 D-cell Maglite flashlights and the other fits the Mag Charger rechargeable flashlight. I have one of the older model upgrades that's rated at 700 Lumens, and it's amazing, so I can't hardly imagine what the 1000 Lumen model can do!

This image is essentially what they both look like. The connector plug end is different.
These LED's are Multi-mode or Single mode capable. In Multi-mode, each depression of the on/off switch sets a different brightness level. In single-mode, it acts like a regular flashlight with one brightness... REALLY BRIGHT!
Add a 4, 5 or 6 D-cell Maglite to the order
