The Surefire Backup

[mspeterson]

Here are some beamshots...review in progress......

 

[mspeterson]

The test lights:

Surefire Backup ...1x123
McLux III PD-S (from the first wave)...1x123
Muyshondt Nautilus Q5...1x123
Malkoff P60 Q5 dropin in a Surefire frankenlight...2x123
Fenix P1 Lux III (a dinosaur!)...1x123
Fenix L1D Q5...1xAA


Here is the set up:

Beamshots were taken 22' from the target wall, centered on a window backlit by city lights- no white walls here! The target wall is 13' wide, the top of the window is 7' 8" high, and the window itself is 5' 4" high. Manual settings were used on the camera to provide better comparison. The first set of pics highlights the hotspot, the second lets a little more light in to give an idea of relative spill, and the last set provides a direct comparison between each light and the Surefire Backup.

Here is the target. lights out:

very nice, thanks alot... BTW, are you running 3.7v cells on the L1D Q5?

Primaries only, sorry! The L1D is running a fresh Energizer Lithium.

Nice job.........beam looks nice and white.

Thank you for the beamshots. The E1B reminded me of a true spot light. The spot diameter is just right. Have you done a run time on it?

 

[WadeF]

What exposure did you use for the beam shots?

 

[Gaffle]

I am curious about the lux readings of the E1B.

Thank you for the beamshots. The E1B reminded me of a true spot light. The spot diameter is just right. Have you done a run time on it?

Nothing with any accuracy...I ran it through a battery last night, I would guess that the stated runtimes are conservative by a little. At approx. 100 min. I found that there was no difference in hi/low anymore, acted like a single level. The brightness gradually diminished, not a sharp drop in level. It sat for about 25 min. on high on the table, got toasty but not hot to my hand. Held it for about 30 mins. on high, and in hand it got slightly warm.

I hope Surefire makes a two cell version of this light, same levels with extended runtimes....guess that will be the new defender?!

I am curious about the lux readings of the E1B.

I post readings, compared to some other lights like the SF L1, P2D Q5, etc, when I get mine. LUX meters vary from meter to meter, at least with the basic ones most of us CPF'ers use, so you can only really compare readings taken on the same meter. On my meter I'm guessing the E1B will be in the 4,000LUX range.

What strikes me most about the photos of the E1B is how "natural" the illuminated area's colors appear in the spill area. It's really remarkable how "natural" it looks compared to some of the other lights !

The E1B certainly is shaping up to be a dandy little light if the UI appeals to one......and it does to me !

Thank you for your fine review !

- my best regards.

Still wondering if the exposure was locked for the shots, or if the camera was on auto.

It had to be on auto, because in those photos the P1 (Luxeon) is nearly the same brightness as the Malkoff Q5. In reality the Malkoff is at least 4x as bright as the P1, if not even more.

Looks to be auto, for the dark room shots.

Depending on what browser you use you should look into an EXIF viewer plug in. I have only to right click to see the image information.

Ah! So that's how you were getting it in the other topic. Can you get that EXIF viewer plug in for IE?

People who take beam shots should post if they are shooting in auto, or manual and at what exposure. Other wise the beam shots may mislead people into thinking one light is the same brightness as another, etc.
