In praise of L.E.D.s

Can't compare 2 items on different days.
On the left - 12W (early) "Energy saver". Took minutes to get this "bright" and, though not hot enough to burn, WAY too hot to remove without protection.
On the right - (Coincidentally, same firm) 7.5W LED still cool enough to remove 15 mins later.
My money's on LED.
