Reason for enclosed fixture ratings
What is the reason your A19 bulbs can not be used in enclosed fixtures? Why am I able to use a 60W incandescent bulb, but not your bulbs which are only rated at 10W?
Our 10W A19 lamps may not be used in an enclosed fixture. The reason is that enclosed fixtures do not provide sufficient free airflow to keep the bulbs cool, and may lead to premature failure.
Although LED bulbs emit less heat than incandescent bulbs, they are much more sensitive to heat due to the internal electronics in the LED bulb. An incandescent bulb is essentially made just of glass and a wire element coil (filament). Therefore, although a 60W incandescent bulb may work fine in an enclosed fixture and emit lots of heat, a 10W LED bulb emitting only a fraction of the heat may still be detrimental to the LED bulb because its components are much more sensitive to heat.
