Low energy emitting light sources

I would like to know if anyone is using low energy emitting light
tables such as flexible light panels by CeeLite
<URL:http://www.ceelite.com/> or Konica
<URL:http://www.konicaminolta.com/tech_info/newlight/index.html> or
others for exhibiting paper negatives or other transparent media.

I am interested in learning about the spectral curve of these lights
and if they provide accurate color rendition for transparencies
placed over them; if no heat is generated; and if these devices
provide sufficient illumination to observe the objects. Any
information would be appreciated.
