Fluorescent Types and Differences

hey all just a thread about fluorescents

what are the different types, i know a few like triphosphor, t5, and CFL's

i was wondering what is the difference between triphosphor and T5 if anyone knows or could tell me?

one difference i noticed with CFLs that are up and down instead of spirals is that they have dark lines along the length of their light projection, and perhaps moreso when warming up only for a little while, i dont notice so much with them all on

is spiral cfl slightly better for distribution? i think i got that from somewhere

i noticed the 42w straight cfl are slightly longer than the spiral ones which is a slight advantage for the spirals

what do you guys use yourselves?

T5 lamps generally last for 20,000 hours, as compared to T8 lamps, which last for 15,000 hours.[17]

The rated life of a CFL ranges from 8 to 15 times that of incandescents.[10] CFLs typically have a rated lifespan of 6,000 to 15,000 hours

but what about lumen output?

The luminous efficacy of a typical CFL is 50–70 lumens per watt (lm/W) and that of a typical incandescent lamp is 10–17 lm/W.[18] Compared to a theoretical 100%-efficient lamp (680 lm/W), these lamps have lighting efficiency ranges of 9–11% for CFLs and 1.9–2.6%, for incandescents.[19]

Since T5 are smaller than T8 bulbs, but produce roughly the same amount of light, their surface luminance is higher than T8 lamps. Glare can be an issue, especially with high output bulbs (5000 lumens), but can be mitigated by placing the bulbs out of direct line of sight, or using louvers or diffusers.[15]

54 Watt T5 = 5000 lumens

CFL watts: 30–52 lumens = 2,600

incandescent watts: 150


Decent small pointer, answering my own question for board substance, peace

does anyone have the luminous efficacy of T5 and T8 lamps?
