The present invention relates to ultra-fine inorganic fibers and a method of producing the same. With the base-engaging member sandwiched between compression plates, relative movement of the compression plates toward each other compresses and expands the base-engaging member diametrically to engage and grip the interior sidewall of a light bulb base for extraction from a socket. The side section is adjacent the traffic section. Humidity and temperature sensors may be placed outdoors and indoors in the space having air to be dehumidified, temperature controlled andor mixed with outdoor air.
