    These R7 bulbs usually get used in floodlights. We've got an uplighter than uses them. When I looked a few years back the LED replacements were bulky plastic "corncob" things with a load of individual LEDs on - I assumed the space in the wide bit was for the electronics to take 240v down to something the LEDs would run on.

    The Uplighter has very limited space and I concluded they wouldn't fit, and bought another Halogen (the last one in the house, but for a light that was almost never used). Now the lamp is being used, thebulb failed and I looked again and found these Phillips bulbs. Only available up to 900lm/60w equivalent but how do they work - theres clearly no space for any electronics in there?
