Well i just bought a surefire E2e, and WOW it has crazy spill. What do you guys think about it? To me its like a spotlight because i barely can see anylight except for the hot spot
Spill on the E2e?

So it has crazy "spill" but it is like a "spotlight" and you can "barely can see anylight except for the hot spot"... that too me sounds like there is no spill at all...

Yep, the E2e doesn't have all that much in the way of spill. Certainly not as much spill as the P60 or even more modern reflector-based LED drop-ins.

I guess there is nothing i can do about it is there? Im thinking about returning it if i cant fix the spill.

An F04 will make it a nice light for walking around.

Can you clarify if the problem is spill or the spot? It sound like you are saying that the spot is too tight and too bright - is that right?
Let me say that having a whole slew of these right now that every run of the e-series head has a different beam pattern. Most of them are a pretty nice blend of spot/flood - although the flood part of the beam is very wide.
What bulb are you running in the light right now? The stock 60 lumen MN03 - because that bulb has a pretty big spot. If you want to move into rechargable LiIons - The EO-E2R (150 bulb lumens) will run on IMR16340 and RCR123 @ 0.85A and has a pretty big spot.
I would definitely consider the F04 diffuser which gives you the best of both worlds. Room filling flood for close-up and decent throw for outdoors.

The E2E has a shallow reflector design. The angle produced if you draw a line from one rim of the reflector, to the filament, and then to the opposing edge of the rim of the reflector is more obtuse than most tactical lamps. In fact, it IS one of the few configurations I am aware of that actually does produce an obtuse angle. Most other reflector designs produce an acute angle. I really have no idea what point was trying to be made originally in this thread. The comments all seem to be in opposition to each-other.
The ratio of spill intensity to beam intensity on reflector loaded incans is pretty much always greater than when measuring reflector loaded LEDs. This is caused by the great differences in emission patterns between an LED and a filament.
Roughly Translated (assuming all conditions are as equal as possible): Incandescent spill beams are dimmer than an LED producing the same lumens. Incandescent center beams are brighter than an LED producing the same lumens.
I have always considered the E2E to have a very ideal spill beam behavior for use indoors as it illuminates nearly your entire field of vision, compared to other lights that are more like a cone of light.

Yea, I also like the spill of the E2e. It was never meant to be a throw light of course with a 19mm reflector. It was designed with compactness in mind. With the more powerful 9v bulbs and can be a reasonable medium range light as well, while still retaining the sidespill.

Can someone post some beamshots of the LF bulbs compared to the regular bulb? Thanks.
Check this thread for some comparison beamshots: http://www.candlepowerforums.com/vb/showthread.php?t=259964

+1...I find the spill on the E1e/E2e more than adequate...it's not an L4 or M60F spill, but for it's size, is plenty, to make sure you don't trip on anythnig.
Speaking of spill, I thought of coming up with a way to "measure" spill...it would holding the light at ~waist level (like yer walking with it), and you would measure where the light stopped in relation to the vertical plane at which it was held.
So, if our average hieght is 3', and the spill stopped 6" in front of your feet, it would have greater spill than say a light where the spill stopped 2' in front of your feet. I know they already use the degree's measurement, but this might b a way to better quantify it in laymens terms???
Now we just need a method of translating the distance to a more reconizeable measurent system...such as you start at 10, and subtract 1 point for every 6"/.5 ft. that the lights spill is away from it's vertical axis.
So, if the spill was at you feet, it would be a "10", and if the spill died 2' in front it would be a "6".
And, we could do some beamshot's and post the results some where with a white/black measurement on the floor...maybe I'll work on a few this week-end and see how feasible it is???
OK, brainstorming session over...

Wouldn't an easier way just be to measure and compare the total beam diameter at - say - 10cm from a wall?

The way I measure spill angle is to solve for a triangle. Point the light at a wall and measure the cross-section of the spill. There is a right triangle formed from the center of the spot on the wall, to the edge of the spill, back to the head of the flashlight. That angle x2 is the total "spill angle" of the flashlight. You can see the results of said measurement in the Behemoth Tactical Lego Shootout 2009 thread 
If you don't know how to solve the triangle, there are plenty of web-sites with built in calculators, (careful, some aren't accurate to very many decimal points).

Does the height of the filiment make a difference? Do any of the LF replacement bulbs have a different height than the SF original?
Actually, for the OP, if you haven't, you might read a little here about the LF (Lumensfactory) replacement bulbs. They offer some choices that are different from the two SureFire bulb options for the E2 incan light.

Is your lamp base blue? What you're describing sounds like an MN02 beam.

Its the stock lamp that came with it. I bought it new from cabelas.

LF replacement lamps are pretty much all designed to replicate proper filament position for given reflector applications. As the size of the filament changes, one could argue that the optimal position may be slightly different than it was stock, however, I doubt that the variation in filament position from SF to LF lamps is of any significance.
Changing the position of the filament in relation to the rim of the reflector (or, the rim of the bezel if the flashlight in question has a particularly deep bezel design, like the "defender" style aggressive crenelated stuff) is what changes spill angle. If you have a maglight with the stock cam-focusing system in-tact you can demonstrate the effects of moving the filament position. Tailstand the light on a table pointed up at the ceiling and adjust the focus while carefully observing the size of the spill beam on the ceiling, you will see it get wider when the bulb is moved forward. Also, if you are very observant, you will also be able to detect that the room will get slightly brighter with the bulb in the forward most position compared to the bulb is the back most position.
