Choose compatible CCFL inverters for your lighting device

CCFL inverters come in all types, including those for used for conventional lighting, as well as ultraviolet fluorescent lighting. To choose the right type of inverter for your products, make sure it's compatible. For example, a UV CCFL inverter should not be used in a product that does not use ultraviolet light.

I recommend: Companies such as Digi-Key and Coilcraft carry many different types of CCFL inverters for all your lighting needs.

Find CCFL inverters with the correct wattage

Wattage is another important spec to consider when choosing CCFL inverters for your products. Too much wattage can easily blow the whole system with a power surge, and too little wattage will affect the strength and efficiency of the lighting unit.

I recommend: CCFL Direct provides inverters specifically for the computer industry, particularly LCD screen back lighting. Endicott Research Group also offers LCD back lighting, in addition to other types of CCFL inverters.

Purchase CCFL inverters that are RoHS compliant

The Restriction of Hazardous Substances, or RoHS Directive, controls the use of specific hazardous materials that may be present in electronic equipment, such as lead, cadmium and mercury. There are six types of hazardous materials in all the fall under this regulation. If you purchase a CCFL inverter that is not RoHS compliant, you could put employees and customers in danger.

I recommend: Most reliable suppliers of CCFL inverters will be able to provide you with RoHS complient products. Mouser Electronics and Microsemi are two such companies. Microsemi also offers a handy guide to choosing the right inverter for your needs.
