So...has anybody any idea as to how long these bulbs will fire up within the acceptable spectrum/range? How often should these bulbs be changed out? Does anyone know how often Dez changes his out?
I agree, though, with $20/bulb, even with a 6-month change-out, that's still a great deal. Usually these bulbs cost me >$100/pc
So anyone has a preference who to order from? I kind of leaning towards the Canadian site (Hobby Lighting).
