12 volt DC Light Fixtures & 12 Volt Fluorescent Ballasts

All lights shown on this page are 12 volts DC unless otherwise noted. Attempting to power them from anything other than a 12 volt battery will probably ruin them. 115 volts AC will certainly blow them up, and make funny noises.

Northern Arizona Wind & Sun has the largest selection of ThinLite 12 volt DC lighting fixtures anywhere, with over 60 models in stock, plus replacement lenses, fluorescent tubes, and DC ballasts.

For lighting charge controllers, see the "Morningstar charge controllers" in the Charge Control Section.

What does lamp color mean? You can see an abbreviation after the lamp number, usually something like XXX/CW. This abbreviation means correlated color temperature. The correlated temperature of a light source is expressed in degrees Kelvin (K) and is a means of describing the appearance or "color" of the light itself. It describes the apparent whiteness of the lamp. Most incandescent lamps have a color temperature between 2700K and 3000K. Fluorescent sources having higher correlated color temperature (4100K to 6300K) are said to be "cool" in color such as Cool White (CW). Sources having a low correlated color temperature (2700K to 3400K) are said to be "warm" in color such as Warm White (WW). Daylight (D) has a 6500K correlated color temperature. Nearly all Thin-Lites are "CW".

Thin-Lite lights are all for 12 Volts DC only unless noted. Black wire is positive (+) and white wire is negative(-).

There is no such thing as a DC fluorescent tube.

All fluorescent tubes are for AC operation. The inverter ballast takes the 12 volt DC input and changes it to the AC that is needed by the fluorescent tubes - it is basically a micro-inverter. Each different wattage fluorescent tube has a different AC requirement. Therefore inverter ballasts are not interchangeable for different wattages or voltages.
