Add a diffuser to any of your existing lights. Could even make a diffuser out of milk jug plastic cut to the appropriate size and fit under the existing lens. My Lumintop FW3A is a very nice flood light. Needs a particularly compact 18650 with no button on top such as the LG HG2s that I bought for it.
What configuration are you looking for? are you looking for a “it’s midnight and someone just turned on the sun in my backyard,” or a pocketable useful flood, indoors, and outdoor out to about 50 yards?
Do you want simple, or complex with a programmable UI with multiple modes?
if you want simple, pocketable, great beam profile, and enough juice to light up a room, get a Surefire Backup MV ($130). Very floody wall of light type profile, but also enough punch to get out to around 50 yards outside. Also, grab a Lumens Factory 18650 body ($35) for it so you can get a good extended runtime and a little extra output.
It’s not sexy, it’s not exotic, it’s just simple, tough, and does what you need it to. In stock form, the high/low are great levels and very useful. I reach for mine most often while tooling around the house after everyone has gone to bed, or while walking out to the out-building (about 50 yards from the house) at night when I don’t want to kick a skunk or walk through a herd of deer. I wound up modding mine with a Hi CRI 5000K Nichia 319A/T and H17Fx driver just so I could have more options, but the stock emitter tint and beam profile was very neutral white and almost matched the Nichia. A 319 fits the stock reflector well, so you know you can swap the emitter down the road if you like (and retain the stock driver).
If you don’t go that route, any of the modern triple emitter lights, like the Lumintop FW03, put off quite a lot of flood for next to no money (around $50).
You might want to check out the Malkoff "Wildcat" on Malkoffdevices dot com. It puts out a lot of light on high, but has a built-in low mode also. You can decide which MDx body length you want to use for rechargeable Li-ion cells. I don't have one, but only because I have several other floody options. I do have Gene's "Houndog" (thrower), and it's a brute. I think that there are beamshots on his website.
I just made the same search and ended on a Fenix SD11 dive light. Dive light you say? Well it's meant for under water camera work. Even comes with a camera mount. Two levels 500 & 1000L with claimed run times of 3 1/2 & 2hrs and throws of just 30 & 45 meters.. And as a dive light I doubt heat would ever be an issue sadly I don't dive so I guess I'll find out if heat build up causes step downs. On sale now for under $100 and uses standard 18650 batteries. I'll post a review once I get a few hours of use under my belt.
