I need to generate a lot of light with the same spectrum as the sun - 10,000 Kelvin (10000K). I have searched around for hours, however all full spectrum lights available are either 5500K or 6500K - but I need 10000K..

For reference I've searched Amazon for hours but I found nothing. I searched other places and the only such bulbs I found where for cars or fish tanks.

Therefore, I'm interested in learning what technology is available to generate this kind of light spectrum?

I am not asking for specific product recommendations but rather the general category of such products. For example, one person recommended a metal-halide discharge lamp.

Are there any other options?

  • \$\begingroup\$ Maybe you could combine the 6500K lights with some ~450nm (royal blue) LED light. \$\endgroup\$ – Spehro Pefhany Feb 27 '15 at 21:50

    \$\begingroup\$ The Sun produces light at 5900K. Rayleigh scattering pushes the color of the sky past 15000K. \$\endgroup\$ – Ignacio Vazquez-Abrams Feb 27 '15 at 22:05

Probably your best bet technology-wise is a metal-halide discharge lamp (which will require a matching ballast). Specific product recommendations are off-topic here, but I suspect this is the right technology for the job.
