R.I.P. Gone, but not forgotten.
It would be fun to light one with a couple hundred watts of LED and the other with a CFL rack to just check the difference in groth. I so love actual experiments where you can see a difference or not see a difference dpending how the results come out. Always my best learning experiences. I must be from Missouri isn't it the show me state.
Something like that would go nice under the GLH.
