Quoted from JPscranton:While on the subject of used bulbs, I would rather use used GE44 bulbs than new Eiko garbage. Those GE bulbs last 20 30 40 years in some cases and have a nicely diffused cutoff line where the Eikos have a sharp cutoff (much like HID headlights in a car). Used GE bulbs FTW.
Depends on your application. We use Eiko bulbs in our scopes and tooling and love the cutoff. Can't have lost lumins or diffuse dimness when the bulb is nearing end of life that throws off results. Much rather have it full brightness and then just die completely, like an LED.
Greenhouses...makes perfect sense now!
