Are the true measurements of a Flo. bulb pin to pin, or is it just the length of the bulb itself? Need to replace the bulbs in my HO
fixture, but not sure what actual length the new bulbs need to be. My current bulbs are 34" pin to pin.
Where do you all get your bulbs? Looking for 36" 6700K, and 10,000K 39 watt T-5 HO
bulbs of good quality.
