A "red fluorescent" would be preferable to an incandescent.

Does one exist?

I see much out there about "Warm White" fluorescents... Below you will see two graphs of Warm White spectra, and the incandescent spectrum again.

I see a lot of orange and yellow in the Warm Whites, but it looks to me like incandescents still provide much more red.

There are fluorescent agro-tubes that are said to put out strong blue and red, but again, these come at significant cost for bulb + fixture, and their superiority as a source of red is questionable anyway.

So I'm back to the question - Why not use incandescents if they are a better source of red light than even "warm" CFLs provide? Yes, they are less energy efficient. But if it's red light I seek...

Perhaps bad experiences or anecdotes about incandescents have prejudiced you against their use, regardless of their potential value?

Don't be an anti-incandescite! *grin*
