Surge Protector - strange reaction to light sources?

[QUOTE="Tom.G, post: 6167312, member: 581973"] That is typical of Neon lamps at their end-of-life. As they age their ionization threshold voltage increases. The external light adds a little bit of energy to the gas, lowering the threshold voltage. This can also be demonstrated with new Neon lamps by applying a voltage just below threshold and then shining a bright light on them. p.s. Typical Neon lamp lifetime is 2000+ to perhaps 25000 hours and decreases with increased current. I have about a dozen outlet strips here with about 20000 hours on them. One lamp has failed and 8 others are very dim. Quality control seems to be lacking. [/QUOTE]
