Hi all, i was hoping you could clarify this for me.
I've noticed that standard 24W 2ft HO T5 bulbs are rated to output about 2k lumens and nearly doubles with extended bulbs and therefore wattage. (4ft-54w bulbs)
As known 54W HO T5 bulbs are rated to output about 5k lumens. My question is as you may have gathered from the title, Is this output based from the entire length of the bulb overall or as measured from directly under the bulb?
Thank you.
