hey dear friend!!!
As in mass per unit volume, no not really.
Non-codirected photons (takes two or more) do have rest mass in their center-of-momentum frame, so you could say that all the photons in the Universe (for example) represented some non-zero density, but it would be a very small value, much smaller than the density of matter-mass.
i hope it may help u!!!!!

Heya!
Q. Does light have density
A. As we know, Light has no mass, therefore no mass per unit volume. Light is an form of energy and thus 'energy density', but it does not have mass or mass density.
Conclusion:Hence, we can say that light has a certain 'density'
Hope it helps
