are all e2dl's like this?

[nitebrite]

hi,

i got a kx2c a couple weeks ago and it is pretty much all throw.

yesterday i got a e2dl. this thing is the new l4 imo! it floods more than my l4 and throws forever. it literally lights a football field! i thought the e2dl was just a kx2c? the bezel has no markings other than "caution hot surface". are they all like this or is this another surefire i lucked out on? the beam shape and color are superb also.

thanks,
nitebrite

Check out this post by Prime77. The last 2 pics show the E2DL and the L4, beamshots.

I dont own a L4 to compare, but i thought my E2DL had bugger all flood, however it does throw really well.

thanks.

those pics are right on.

my e2dl is a brand new two speed. it does not have a thick optic like my kl1. i thought that is what a tir is?

in another thread we were discussing if surefire updated the led in the l4 when it went from 65 to 100 lumens. according to size15s who i take to be the expert, they may have changed bins but not dies. he stated that they mostly measured the output better across a wider range of samples. i tried a new l4 and it seemed only slightly brighter than my 65 lumen model. my l4 had 20 minutes on the batteries.

maybe my e2dl seems so much brighter because my specific l4 is not outputing nearly 100 lumens. i don't know what is with my kx2c though.

in close quarters the l4 has more throw.
outside the ed2l seems much brighter. i think it has plenty of spill. in the pics even though the l4 covers a larger swath it seems dimmer to me.

Hold on, are we using the same words to mean the same things here?

The E2DL should always have more throw than the L4 - throw is about how far the light goes. You can't see throw at close distances.

Spill is about how much light goes outside the hotspot.

The L4 should win the flood (spillbeam) contest but the E2DL should win the throw and overall output ones.

SureFire has the ability to tune or focus each individual bezel during assembly (that's why there tends to be a gap between the bezel segments). Each bezel (TIR optic mounted in the forward segment) and LED (mounted in the rear segment) will have a sweet spot that produces the best quality beam. Some are tighter than others. As the two segments are screwed together and wet-sealed (thread locked, glued, whatever) the assembly technician tunes the beam sometimes leaving a larger gap, sometimes basically no gap at all.

This goes for the KX1 and KX2, the E1B and E2DL, the KX2C and X300, as well as the L1. They are all essentially the same (AFAIK) but can produce very different beams depending on where the focus is set and what works best for each individual combination on components.

thanks.

my e2dl has more spill than my kx2c. it does not have as much spill as my l4. however, the spill the e2dl does have is brighter than that of my l4. hope that explains.

i got a little carried away when i mentioned it throws/spills "more" than the l4. not as much spill but brighter spill and still plenty of it.

it would be nice if they kept some consistency. so you could know what you are getting each time.

For lighting up a room or an area around you the L4 has the perfect (flood) beam for this,this light isn't called "a wall of light" around here for nothing.
Now if you want to throw a beam at a tree say 500ft or so the E2DL does it easily,but i see what your saying about the side spill from the TIR optic.I think it's very usefull.

Take care

i'd still like to know something. my l4 says 65 lumens in the manual. if i go look for one today can i expect to find one that is 50% brighter? i tried a new one and it was not that much brighter and my batteries were used. someone said in another post that their new one is twice(?) as bright as their old one. maybe mine was just a good example.

i am wondering because if other people have much brighter l4's than mine maybe that is why i think the e2dl has such good flood. if my l4 was a lot brighter i might not think that.

i just don't know if there are brighter l4's than mine. i guess there is no way to tell besides comparing a bunch of them. according to sf cs they changed it. i don't know.

nitebrite,

Your L4 (KL4) is 100 lumens not 65 lumens. The output didn't change - just the rating.

Due to the extremely tight time constraints at the time SureFire guestimated the output of several of it's products including the L4 (KL4). All they could say for certain was that the output was at least that of the P60 incandescent lamp. So '65 lumens' was the best they could do in the short time between the actual samples being made for SHOT Show and the catalogs needing to be published in time for SHOT Show. They weren't able to do sufficient output tests in the time they had.

SureFire found/made the time to thoroughly test a large number of lights from production and was able to be confident enough to increase the rating to be more representative of the actual output.

 

[nitebrite]

thankyou so much size15's for being exactly clear on that.

you made me feel real good right now! i was just about to go spend another $175 to get the same light! not that two of them would hurt, but i'd rather get something else right now.

Sorry to resurrect an old thread, but I was searching around the forum and had a follow-up question.

Do you know if the same holds true for the x300? I have the older (advertised as 120 lumen) version. Does the newer (200 lumen) x300 actually have produce more lumens or does the new rating just do a better job of representing the actual output?

Thanks,

I'm not certain. My gut tells me that it is a different situation where a current X300 will be obviously higher output compared to an original one, but I will try to find out for you

Thank you; I would be very interested to know.

I just bought a Surefire E2D Led Defender. When I turned it on I noticed the beam wasn't a perfectly round circle. I check out some review on youtube and every Surefire E2D Led Defender review had a perfectly round spotlight beam. Should I return my flashlight to Surefire or is this normal?

How bad is it? Post a pic if you can.

fourtyounce48, you've posted this query in another thread, plus created a new thread on this issue. This is cross-posting, which is against the rules. I've merged those two threads, so discussion of this should continue there.
