Surefire P60 Xenon stands up to a 170 lumen LED...Beam shots.

[PinarelloOnly]

Beam shots are at 82ft give or take an inch or two from my SF C2 to front
of shed. Doors to shed are open to also show how well these D26 lamps
can still light up a room at distance. 65 lumen Xenon wins. IMHO. BOGUSA
Prem. Plus LED seems to drop off in throw after 60ft.

Note: I am not a fan of smooth reflector LED lights, although some have
outstanding throw, the tight hot-spot beams have a lot to be desired
when using them outside. So, I can see why OP reflectors are the choice
of most manufactures and after market vendors.

Notice the 65 lumen Xenon (1st pic) is throwing a touch more light. Very Impressive.:wow:

The torch lumen value of the two lights is probably similar. Nice beamshots.

 

[ampdude]

Great pictures, that's about what I expected. Besides it being obviously brighter, look at all the detail in that picture compared to the LED. The P60 rocks.

 

[Paul520]

Nice shots! Yes, with the LED, colors appear washed out.

 

[Outdoors Fanatic]

That's pure Incan power baby!

 

[roymail]

Very interesting... thanks for posting this comparison.

Have you noticed what these P60 modules sell for on BST? I saw 3 of them go for $12.00 not long ago. I have several set back but they're not for sale.

 

[ampdude]

People all over buy the incan Surefires and then dump the lamps for next to nothing so they can run out and buy the latest binned led drop-in, sometimes for as much or more than they payed for the SF to begin with. It's a great time to be an incan fan!!!

 

[EV_007]

Preachin' to the choir, but amen to that. Nice demo.

 

[Fizz753]

Stole your images and animated them, hope you don't mind.

 

[Illum]

your LED has a very beautiful tint to make this kind of comparison:huh:

 

[mdocod]

I hate to say this but:
Due to the characteristics of emission patterns on an LED, a larger percentage of emitted light escapes as spill light rather than concentrated into the beam when compared to an incandescent bulb configuration.

As a result, taking a beam shot that illustrates the difference between the performance of just the concentrated beam alone does not *always* accurately compare an LED and incan.

While I personally love incans, I have also become very fond of the stronger spill light found in LED lights in similar output categories.

I can almost guarantee that for every apparent lumen that LED lacks compared with the P60 in the photos above, it is being emitted into spill light that the camera has not captured but eyes would see.

Sorry,
Eric

That's cool Fizz, you should label which is which though.

nice work with the animation, i think it does well to illustrate the different beam patterns and the difficulty of comparing the output of the two.

I sorta cheated, I used this nifty program to do the animation for those who are curious. Not sure if it can do text haven't really looked yet. (err just reading the program description it can )

Add image 1 add image 2 set delay, push the button. That is pretty much it.

According to the camera data given, the white balance for the P60 shot was set at "Incandescent", and for the LED shot the setting was "Flash".

For a more accurate comparison, you need to use the same settings for both shots.

 

[mdocod]

Hello DM51,
not sure if that's a good method or not when comparing the 2. If you set it to "incan" for both, the LED will look in the picture FAR more blue that it looks to our eyes in actual use. And if you set it to "fluorescent" or other high color temp setting, the incan would look like a red filter was installed over it in the picture, drastically different than it looks in real life. If you choose only one setting, it would severely favor one light or the other.

The reality is that the eye works much like the auto setting on the camera, and is very capable of adjusting for different "white" light sources. With this in mind, it makes sense to try to use a white point setting close to the light source for comparisons. Even with the white point adjusted properly in the photos above, we are still seeing the richer contrast provided by the incandescent as expected.

in my experimenting with beam shots, i've personally found that locking in a white point is best when you want to compare lights in the same category, incans vs incans, or LEDs vs LEDs. It can be used to illustrate how overdriven a particular bulb really is compared to another (white vs yellow appearance, etc etc). Or show tint variations from one LED to another. But a "blue filtered" or "red filtered" shot of either doesn't do much good.

Hi,

I am not a Photo Expert but i see that noise reduction (NR) is On at first photo. So this gives a non foggy/noisy seem. And i see that Sharpening is set Auto, so sharpening over a foggy/noisy photo makes things uncompareable.

Just my opinion,

Led vs Incandescent will go on forever....

 

[ampdude]

According to the camera data given, the white balance for the P60 shot was set at "Incandescent", and for the LED shot the setting was "Flash".

For a more accurate comparison, you need to use the same settings for both shots.

Yep, in this case the LED would look even worse. I noticed it was whiter looking than it should be.

Eric

+1 for Eric, at least someone else understands the camera.

This is correct in that; if I left the white balance set to incandescent for
the LED shot, the end result would be with the LED shot being blue
because the camera is looking for incan light and adjusting the tone
accordingly.

------------------------------------------------------------------------
To the rest of the "expert" opinions out there,

The two shots you see took about 30 min of prep getting the settings
to where the final shots look as if you were standing there when they
were taken. Also, remember this is all over a distance of 82 ft with the
lens fully zoomed in (D50 kit lens and Bogen tripod w/fluid head).

If anybody is reading into the settings as some are, the settings in "auto"
actually produced the best results (more accurate). The in-camera settings
that I posted for each picture are mainly for the many other Nikon D50
users out there to use as a "guide" for night shots and not to be judged,
read into or used if you own a different DSLR.

Posting the full in-camera settings is the norm on the camera forums and
I wish others would do it here too because sometimes you do not know
what your looking at as far as accurate lighting bouncing off of a subject.

AND FYI: The "flash" setting does not mean the flash was used...ONLY the
white balance setting was adjusted to "flash" which is the closest light
definition that the Nikon D50 will recognize for LED light.

It turns out the Nikon D50 did a very accurate job at taking the LED photo
knowing what light it was "seeing" (modern flash/LED) and adjusting it with
very very accurate results. Again the settings in "auto" did the rest of the
work with no flash actually used.

The purpose of my post was to show the incan power of "throw" and
to show it somewhat accurately at a distance between two different light
sources with functionally the same OP reflectors and not against some wall
which others here find is the way to tell the story of flashlight
performance through a camera lens. Some here I am sure will a test that,
accurate results of a light beam, at night, through a camera lens is a very
trying and difficult task.


Fizz753. Awesome animation!!! Thanks.

 

[DM51]

No need to fly off the handle. I was not suggesting your results were wrong. The exposure times and apertures were the same, so the relative brightness is accurately compared.

I was merely suggesting that the color balance settings, being different for the 2 shots, renders them more similar in tone than they would actually appear to the eye. And of course I wasn't suggesting that you actually used the flash.

I think if I had done the test, I would have set the color balance to daylight for both shots. The contrast in color temperature of the lamps would then be more clearly seen.

You succeeded in showing the relative throw of the two lamps, which is what you set out to do. My comments were in no way intended to discredit your findings in that. I have taken a few beamshots at night myself, so I am aware of the attendant difficulties.
