Hmm, not bad. However, at 20 to 30 percent better efficiency
than mercury-vapor it would be right in the range of MH or
fluorescent if I remember correctly. Nothing what I would really
call spectacular. One of those 5,900 watt bulbs
must make _a lot_ of heat! However, it seems to be a good step
forward to more intensity with smaller bulbs. 

This sounds promising, especially if the color spectrum is as good
as is claimed in the article.
Thank you for the information, George.
