Officiel EM4 VARIOUS BRANDS USED BUT STRONG DIGITSTD X1

ConditionTEST (datasheet)

TESTED AT 250V

As it is hard to tell how bright is a tube, I used a non scientific protocole to determine it using the phone app "luxmètre".

Always expect tubes to be a little less shiny than in photo. ALSO, due to contrast on the camera, you should not compare pictures on my other bids. Trust me, theres a real/huge difference between a 20lx tube and a 100lx one, that picture doesnt show clearly...

I tested 40 tubes this way so you can compare results obtained through all the bids of my EM4.

I unsealed some Miniwatt EM4, tests values were from 64 lx to 150 lx.

0 lx = no light
