[Technical Review] J5 Tactical V1 Pro

This model is a JOKE. No where near the 300 lumens as claimed. I sold off my 2. Only bought because it looked cool. Output plains SUCKS!!!

The reviewer, Terry Oregon, measured:

Fully charged Olight 14500 battery (at 4.2V)

High: 134 (manufacturer spec 300)

Low: 35

Fully charged AA Panasonic Eneloop Pro

High: 53

low: 13

So yes, it’s way off it’s claimed specs.

Yes and NO. The lumens dropped quickly from 300 lumens. So output was not constant. My mine was defective???Either way, I sold them off.

The lumen maintainence is not so good. I think it is due to the LED thermal resistance is too high. Have you ever use the Integrating Sphere System to test it?

Prohibitively expensive.

What would the Integrating Sphere tell me that the Texas Ace Calibrated Lumens Tube doesn't?

I finally took mine apart. The pill is hollow and the mcpcb has Latice Bright written on it so its safe to assume the leds are Lattice Bright and not XP-G.
