Review on 💡 CEC Industries C2A Neon Indicator Bulbs, 105-125V, 0.25W, Wire Terminal Base, T-2 Shape (Pack of 10) by James Stevenson

Revainrating 1 out of 5

Electrodes not parallel

All electrodes were not parallel, some strong with tips almost touching the inside of the bulb. This results in ionization being confined to the tip of the bulb only. Changing the bias current (from 240kΩ to 24kΩ R-Series, 120VAC) didn't help. The picture is the best (most parallel) in the group. Uniform ionization was not achieved.

Pros
  • Consistent test results
Cons
  • Newer model could have been chosen
