I am highly satisfied with the spiral daylight lamp. For my windowless, 6 sqm large study I get daylight-like conditions, what the mood is good. I also wanted to test by purchasing this lamp the Studio suitability for still images. But it is also well available. Since I can not find my pocket spectroscope, I can not say whether it is a full spectrum lamp, unfortunately. The photo professional should inform in advance in this regard. If I can still identify the spectrum, I will add a response with it.
Addendum 08:04:11: The spectrum of this lamp is not continuous. It has three maxima: in red, green and blue. In between are z.Bsp. in yellow or orange range no colors emitted.
