Better yet, check to find one with a high CRI (colour rendering index).
The
closer the number gets to 100, the closer it is to actual spectral light
from a
continuous source such as the sun or an incandescent bulb.
I thought about that, but settled for a locally bought one, lucky
to find a 100 watt equivalent for this cheap experiment.
