Cheaper bulbs, definitely. I had a corner display cabinet I tried to switch over to using an LED bulb; the compartment for the bulb was nearly sealed and also lined with reflective materials, so the exterior got hotter to the touch than it ever did with an incandescent bulb. Damn thing started flickering and malfunctioning a few months in. Tried another LED bulb and the same thing happened only on a slightly longer time frame. Finally just gave up and went back to an incandescent bulb.
