Question about my lights
I have 2 - 48in shop lights attached to my plant stands with seedlings directly under them. In one of the shop lights the bulbs are Sylvania wide spectrum grolux. In the other are GE wide spectrum plant and aquarium. The Sylvania bulbs are new this year (the whole shop light is new) and they are very bright. The GE bulbs seem dim in comparison. They are the same bulbs that I used 2 years ago, although last year they were not used so they were used a total of 4-5 months.
Sorry, for being so long winded. My question is, are the GE bulbs much dimmer because they were already used? Or is it the type of bulb, or could it possibly be the shop light itself? Should I get new bulbs?
