Convoy L8 Battery Test: QB26800 brighter than the stock battery?

In this video, I test whether the Convoy L8 is brighter with a QB26800 (Queen Battery) or the stock cell. I'm not sure what brand the stock cell is. It was included with the light and had a bright green wrapping.

I used the 'lux' android app for this test. My Opple Light Master Pro has arrived now so will be switching to this for future tests.

Results: no difference in lux readings with either cell

These 26800 cells are challenging to find on the market currently. I managed to get one from an Australian supplier for $30 including shipping.

I'd love to get my hands on a 26980 cell, which is the same diameter as the 26800, but a bit longer. Unfortunately, I can't seem to find one anywhere. There could also be issues finding one with a high draw capacity (30A).
