How often do you change your flowering bulbs?

I use 1k hps digilux bulbs in my flowering room.

I think I'm going on my third or fourth run with them..

Each run is 9 weeks max...

Just wondering for max yield, if i have another run left in them and how many runs do you guys go before swapping out for new bulbs for maximum yield

I use P LL and replace every 12-16 months.

Its all about that loss of lumens. Every setup and bulb type has variables, but I used to change my bulbs every run when I was after weight. No different than most commercial growers replacing the bulbs every run. Used to sell bulbs by the cases when I was running a grow store..

Lumen loss is gradual and expected, but unexpected is the more rapid loss of the enhanced PAR spectrum we all pay extra for. The wider spectrum is produced by esoteric "doping" of the bulb atmosphere, and those materials have a much shorter lifespan than the base bulb. In particular, those expensive blue HPS bulbs almost get yellower by the minute...

Do yourself a favor and ditch the bulbs. They are antique. Pick up some LED lighting fixtures. My plants are in LOVE with LED. They do NOT have to be expensive as in the past. This is what I am using, I have 4 of them and increased my production dramatically. I got 4 of these from Home Depot. https://www.homedepot.com/p/Commerci...2161/302456569

They probably don't put off much heat either?
