12V Transformer Applications & Features
Low voltage lighting is a popular choice for a variety of applications, and is often seen in recessed lighting, under cabinet lighting, track lighting, landscape lighting, pendant lighting and display lighting applications. With lower voltage requirements, light bulbs can often be smaller in size and fit into smaller fixtures without sacrificing quality.In fact, some low voltage bulbs offer features uncommonly found in line voltage. The MR16, a popular low voltage light bulb, offers multiple beam spreads from a narrow spot to a wide flood. The variety of options available make low voltage lighting systems a stylish and affordable component of commercial and residential design.
Valuable 12V Lighting Transformer Information
Indoor and outdoor 12-volt transformers work by converting the standard line voltage (usually 120 or 277 volts) down to 12 volts. [Hint: If you are supplying power to 12v LED lights, you are likely going to need a specific kind of LED power supply, called an LED Driver.]
How Many Lights Can I Connect to my Transformer?
To figure out how many lights you can safely connect to your 12-volt power supply, just add up the total amount of watts you need and make sure it falls between the minimum and maximum ratings for your transformer. (Here's a tip: If you think you might add to your lighting system later, leave a little extra room on the transformer.) Keep in mind that electronic and magnetic transformers may have different maximum wattage requirements. Electronic transformers can use 100% of their rated wattage, while magnetic transformers should generally leave about 20% "extra" to compensate for loss.
