Vho spectrum shift

[SeaSydney]

Hi All,

I just came home and noticed that my two VHO attinic bulbs powered by a WH7 ballast is not as blue as they were this morning. They are about 2" away from two 250 watt 6500k iwasaki bulbs. The lighting has been running for about two weks and this is the first that I have noticed this.

Is the heat from the MH causing this? If not what are the possible causes?

Thank you
Mark

Nah, no heat will cause this. Probably normal as I notice all bulbs that I ever purchased change the first weeks. Normally the most noticeable is an intensity loss.

Thanks Snoopdog. Has anyone else had these experiences?

Thanks much
Mark
