In a rough calculation, a 40W bulb would raise the temperature inside a =
typical trailer by only a fraction of a degree (although it could create =
a local hot spot if carelessly placed). This would only reduce humidity =
by a couple of percentage points and would be quite less energy =
efficient than using a dehumidifier.

Any thoughts on whether a continuously lit low wattage light bulb =
would=20
provide dehumidification or would it put out too much heat inside a =
glider=20
trailer?
