Title: Different electrode glow intensity in green and blue MH lamps?
Post by: dor123 on January 26, 2025, 10:03:23 AM

Why in green MH lamps, the electrodes barely glowing during run-up, compared to blue and other colors MH lamps?
Green MH lamps often glowing greenish during starting, while blue lamps glowing very yellowish during starting.
Why is this?

Are the brands different? Some brands may have slightly different quality differences. If you have different types of ballasts (magnetic and electronic) then you check if the bulb behaves the same on both.

I've seen this with all green MH lamps, that they have greenish color during starting while other colors have brightly yellowish white color from the electrodes.
