По умолчанию Olight I1, I2 and I3 Review with OTF Lumen Runtimes

Here's a picture of all the lights, with two 4sevens lights and a 4sevens CR123 primary thrown in for reference-

Pictured from left to right- 4sevens CR123A primary battery, 4sevens MiNiX 123, Olight I1, Olight I2, Olight I3 and 4sevens Preon ReVo:




As you can see from the image, all of the Olight's tailstand quite well. I had to persuade the Preon ReVo to get it to tailstand for this image, but it was never designed to tailstand in the first place. The Olight's also have a removable pocket clip, which is a nice option to have, since some prefer to carry with a clip and some prefer to carry without a clip.

Operation is simple. If you're familiar with the Quark MiNI series and/or the Preon ReVo, operation is very similar. To activate the light you simple tighten the head of the light until the light comes on. To cycle through the available modes you simply activate the light, then loosen and tighten the head quickly. Basically you're turning the light off, then back on quickly and the light will cycle to the next mode each time you turn the light off, then back on quickly.




Here are my out the front (OTF) lumen runtime measurements of these lights-


Olight I1: (CR123 Primary battery)



Olight I1 vs 4sevens MiNi X 123: (CR123 Primary batteries in both lights)





Olight I2: (Duracell AA Alkaline Battery)





Olight I3: (Energizer AAA Lithium Ultimate Battery)



Olight I3 vs 4sevens Preon ReVo XP-E: (Energizer AAA Lithium Ultimate Battery used in both lights)






Beamshots-

Camera settings for these beamshots were the same for the Olight I2, I3, 4sevens ReVo XP-G and 4sevens ReVo XP-E, but I had to reduce the exposure for the Olight I1 and 4sevens MiNi X 123 because the images were over exposed when using the same settings as the other lights.

Camera settings for the Olight I2, I3, 4sevens ReVo XP-G and 4sevens ReVo XP-E were 1/60, ISO- 100 and F stop 4.5.

Camera settings for the Olight I1 and 4sevens MiNi X 123 were 1/125, ISO- 100 and F stop 4.5.

White balance was set to auto. Click image for larger view:
