So what you're saying is we should buy a L1D, a L2D body, and a P2D body
with tailcap. To cover all of the bases. Since I would need to buy the tailcap/body for the P2D, I think I might just spend the extra 30 bucks or so and pickup a P3D.
Here's a couple of scenarios. Prices are from LightHound, except for the P2D body and tailcap which are from the Fenix-Store. Lighthound doesn't list that item.
L1D $52.50
L2D body $12.99
P2D body & tailcap from Fenix-Store.com $23.50
$88.99 total.
P2D $52.00
L2D body $12.99
L1D body $12.00
L1D/L2D tailcap $6.99
$83.98 total
With this scenario, you won't get a holster (L1D and L2D complete lights come with a holster)
Edit: Scratch that...the P2D does come with a holster...my bad.
I went with the second scenario, because I didn't need a holster for the L1D/L2D. If you wanted to be really cheap, and don't care about the tailcap being just slightly larger in diameter, you can forego ordering the tailcap ($6.99) and use the P2D's tailcap on the other bodies. If you do that, it won't be waterproof unless you install a thicker o-ring.
Yeah, if you don't care about having a P2D setup, you can spend the extra money and get the P3D...but remember that the P3D head is different, only the L1D/L2D/P2D heads are identical. <~~~ Edit: Oops, I see that bondr006 already said that.
Or just get 'em ALL! :lolsign:
I'm thinking about getting another head, because I may end up wearing out the threads by swapping it around the different lights all the time.
