Hi Jim

That has been my operating assumption.  However, an orchid growing friend
told me that output declines dramatically over lifetime and suggested
a yearly replacement.  Mine doesn't burn in the summer so I have taken th=is
as a two year recommendation.

I wish my ancient photography light meter were still operational--I had
it calibrated for'd think an observational astronomer
could do better at calibrating light flux.

Clear skies,
