EL is designed to be small and not too bright. CeeLite pioneered the 3 wire LEC panels. There is a ground shield that reduces EMF on the panel and allows it to be driven brighter and larger panels to be produced without killing the life and without risk of electric shock.
The LEC panels can actually be driven to 600 cd. even though 100-200cd is the standard. 90-100 cd is the average brightness of a laptop screen.
E.L. is really only designed for 50-100 cd, some EL can be driven to 200 cd but the life is cut down dramatically and the EMF is quite large.
So basically it is EL, but higher end. RazorLite and CeeLite use the best phosphor in the world as well as other materials like ITO. If you look at your cell phone buttons, this is EL, very small and only 50 cd.
Watch CNN, ESPN, NBA TV, NFL TV, and a few others and their sets are decorated with CeeLite LEC. Much larger and brighter. even 12ft panels can be produced.
