Replacing your low voltage halogen light bulbs with low voltage LED’s will help you save a considerable amount on your electricity bill.

Before you begin benefiting from these savings, you will need to ensure that you have replaced your transformers with LED drivers, as this is required to power low voltage LED light bulbs efficiently.

LED’s require a driver to operate efficiently as standard transformers often have a minimum load requirement (generally around 20W).

As LED’s consume such a low wattage, they usually struggle to meet this, and therefore fail to work effectively when being used with a normal transformer.

LED drivers have no minimum wattage, so are fully compatible when powering individual, or multiple LED light bulbs. LED drivers are also specifically designed to enhance the life span of LED’s, allowing them to run to their optimum performance. On the other hand, using LED’s with a standard transformer may have a detrimental effect on a bulb’s longevity.

An important thing to consider when purchasing a LED driver would be whether you need a constant current, or constant voltage driver.

If you were planning on using the driver to power an individual bulb, or to run numerous bulbs in series, you would need to ensure that you get a constant current driver.

If however you were planning to run multiple bulbs in parallel, you would require a constant voltage driver.

It’s easy to check which type of LED driver would be most suitable, as all reliable suppliers would state in their specification whether the driver is constant current, or constant voltage.

When changing your low voltage bulbs to LED’s, it’s important to remember to change your transformers over to LED drivers. This is essential for getting the best performance and longest life span out of your LED light bulbs.
