8,2 bulbs - YouTube
I apologise for the poor quality, but you get to see my setup. THE FINAL MEASUREMENT OF THE SINGLE BULB WITH THE 7 BULB CLUSTER WAS 6,600 Lu's. The data shows a 40% increase in efficiency between the single and eight bulb cluster.
@Billixx,
The instrument measurements indicate that the blub cluster behind the clouded glass would be brighter then the one bulb at five times the brightness by a factor of 40%!
