Why is the Sun's Luminosity not equal to the Zero Point Luminosity? I was doing some research and found that the zero-point luminosity was $L_\odot = 3.75\times 10^{28} $, while the sun's reported luminosity was $L_{Sun} = 3.828\times 10^{26}$, according to Wikipedia. Why isn't it the same value? Doesn't the symbol $\odot$ represent the value of our sun?  

Furthermore, when Googling the Luminosity of the sun, it gives $1L_\odot$, which suggests that $L_{Sun} = L_\odot$ when it is evidently not. What's going on here? I'm very confused.

For background, I have little to no background knowledge of astrophysics, and I'm trying to learn about it.

Thanks.
The zero point luminosity L0 is the luminosity of a star whose absolute bolometric magnitude Mbol is 0.
IAU recommends the value
L0 = 3.0128 &times; 1028 W.
If the Sun's Mbol is +4.74, then
L0 / Lsun = 104.74 / 2.5 = 78.7,
which is consistent with Lsun = 3.828 &times; 1026 W.

Your understanding that Lsun &equiv; L&#9737; is correct.
Maybe there was an accidental substitution of L&#9737; for L0 at some point.
Curiously, the number 3.75 &times; 1028 appears in the Wikipedia:Sun sidebar as the Sun's luminous flux in lumens, a quantity more applicable to a light bulb than to a star.
