Re: rule of thumb for relamping please

Top Drop only works if the unit uses the same lamps in both canopy and bench. If yes, this is a nice way to give strong lamps always - switch at about half life.

Never change based on a time period - e.g. annually.

Tie to performance - either meter or track hours and approximate.

Rule of thumb for those tracking hours -

100W lamps - 600 hours

160W+ lamps - 400 hours
