Um ... most LEDs do have the choice to adjust flood/throw right?

[Caesis]

I'm shopping for a decent LED (Looking at the Romisen RC-N3 II)
And I'm just checking ... most modern lights let you adjust the beam, even if it's not advertised, right?

(I know, iNoob.)

Thank you for your time

Surprisingly enough no. I'd have thought it a useful feature to have but even without there is plenty of spill off most of them and a low light mode too.

The Romisen RC-G2 II Q5 can be focused.

Damn.

Okay, thanks.

Question answered. I might have to go back to maglite :S

EDIT: W00t. Thanks rockz =D

Look at the Fenix E20 also, it does have the ability to flood or spot focus.

The answer would still be no, most of them don't give you the choice....

Generally, a light that has a good combination beam is better than a focusing light, since a focusing light has to make other compromises such as beam quality, or complicated (ie. Failure prone) construction, or limited heatsinking ability (very bad for LED's).

Usually, a general purpose EDC light needs to be flood, and larger lights lend themselves better to throw since the larger required reflector size goes better with the larger overall light size. The larger availabe power also let's you reach out further.

Note that you do not get full flood like a zebralight, but it is like mags, where if you flood it too much, it turns into a doughnut.

Coast/LED Lenser make focusable LED flashlights (amongst others) :thumbsup:

+1 for LED modded maglite!

Most have a hotspot and spill. This makes it better than the maglight beam. (It's hard to understand until you see it, just trust me, I have one.) :welcome:

LED Lensers can focus from full flood i.e. no hotspot to a full spot (but still with some spill). I own a P5 and a P14, both can focus from flood to throw

 

[kramer5150]

no, its the opposite... most good lights are fixed beam.

 

[lolzertank]

From the top of my head, I think MagLEDs, the Fenix E20 and the DEFT can change from flood to spot.

An ordinary incan mag probably isn't a good comparison. Most power LEDs have so much more output that they'll beat the mag at both spot and spill simultaneously. You'll find selectable brightness levels more common in LEDs than a focusable beam.

Focusing a power LED has its own set of challenges; It's a flat emission source that needs to be backed by heat sinking material, which makes it challenging to design a reflector focus mechanism for it. Focusing LEDs usually use lens optics instead.

focusing usually means donut hole. why put no light in the center of your focus. the spil beam on my led surefires are brighter than a defocused maglite by a longshot.

please see my beamshots of my LED Lenser P5 here

if there's a doughnut, i sure aint seeing it

And that's the other reason focusable LEDs tend to use lens optics instead of moving the emitter within the reflector. No donut hole. :thumbsup:

LED lights typically have brighter spill than incandescents making the flood option unnecessary on a properly focused LED flashlight.I have never found the flood setting on Mags to be very usefull and most of of my fixed focus LED lights provide more usefull flood without doughnut holes.
