T5 Color Discrepancy

[Hishman]

Has anyone noticed a substantial color discrepancy between T5s of the same make and age.

I’m tweaking my 4bulb T5 and have found that 2 of my Blue+ have a totally different spectrum than the other 2 Blue+. So much so they might as well be different bulbs completely. One is a rich deep blue and the other appears much warmer/brighter guessing due to more green spectrum. All bulb have around 50-150 hrs.

None of the serials seem to have a pattern that I could make out such aa a manufactured date.

Anyone else have this issue?

Yes, T5's will shift in color over their lifespan, and may not all age the same way. Was that your question?

No they are all relatively new post burn in (~50-100hrs)
