Does anyone out there have both the Quasar and Super Nova from Wood Turners Wonders and care to give a reason that one is better than the other? I am getting ready to purchase another lamp for my lathe and see WTW has two fairly comparable lamps...the Super Nova and the Quasar. Price is the same, one has a heavy duty shaft, the other has more led bulbs, more lumens and higher color temp. Any thoughts? Thanks.
