Vulcanmoon, beware that most of the lights recommended here aren't actually floody. Some of them are, but most of them aren't. Do your own research on the review sites before forking over any money.
In order of most significant to least significant:
1. Fix the widely reported issue where the light turns off after being dropped. Reliability is not negotiable because getting unexpectedly plunged into total darkness is a big deal even when carrying a backup light.
2. Remove the 400ms/1000ms...
Well, no. If an electronically controlled switch flickers unless it is pressed 'very deliberately,' then the debouncing logic wasn't implemented properly. That's not user error. It's a bug or a design flaw.
Theoretically it's possible to capture both hotspot and spill with correct exposure by using HDR methods. Take for example this HDR shot, where I was able to capture both the hotspot and spill rings from a 2006 Inova T2:
By tweaking the HDR exposure and gamma curve it's quite possible to...
The picture changes somewhat if you consider eye movement. The total horizontal angle you can see clearly is about 90 degrees if you move your eyes. With a narrow-beam flashlight you'll have to re-point the light to accommodate eye movement, which will increase reaction time to surprises as...

Marketers will say anything if they believe it will help them sell more product.
Sharpened bezels may have some weapons value in trained hands. Not being trained I wouldn't know one way or the other. In untrained hands, however...
Lights designed for long range throw have narrow beams--much like the 2L3W you already have--and won't illuminate a wide area. Beam width and throw are a tradeoff. Wider beam width (flood) comes at a cost in peak intensity (throw) and vice versa.
If you want the option of either flood or...
Word has it that SF has halted L4/KL4 production pending an upgrade. Probably not a good time to fork over money for an L4 given the radical advancements in LED technology since the L4 came on the market--whatever revision SF comes out with will likely be far better than the current model.
Most of the lights suggested here are severe overkill for a yard that size. The HID and hotwire options others have proposed are intended for 100m++ distances. This level of performance is good for American rural and suburban environments but the beam angles necessary for 100m make these...
I don't believe SF makes their optics available separately. You can, however, buy TIR optics designed for the XR-E from Khatod, Ledil, Fraen, and Cree.
How big is your yard and how much of it do you want to illuminate at once?
What kind of light you need is entirely contingent on how large an area you want to illuminate. If your yard is particularly large it won't be possible to get the results you want within your budget, or perhaps even...
It's unfortunate that so few CPF members recognize that the market for lights for forum-aware buyers is minuscule in the context of the overall flashlight industry. Small companies such as Fenix, Nitecore, Liteflux, Dereelight, and similar, make their living by serving users and lurkers of...
