MR16 LED Light Bulbs – What’s the difference?

1 minute read – MR16 LED Bulbs by VIRIBRIGHT Comparison

Unsure of which MR16 you need? This article will answer any questions you might have about these compact spotlights.

The Multifaceted Reflector (MR) is of the most widely used spotlights used in both commercial and residential applications. The reflector inside the MR controls the beam angle of the lamp and is available in different beam angles.

MR light bulbs are extremely popular because the amount of light they offer compared to the amount of energy consumed. Halogen light bulbs consume less electricity than incandescents, but they still use more energy than LED lamps. Many utility companies are encouraging their subscribers to switch to LED light bulbs to reduce energy consumption. In return, consumers see a reduction in their energy bills and less heat put off from these bulbs.

There are two base types for MR16 light bulbs, the GU10 (twist), and the two pin GU5.3 (push to fit). The GU5.3 base commonly operates using 12 volts while the GU10 operates off 120 volts. Voltages vary greatly across all bulbs types so always check the specifications and ensure your fixture is compatible with both the fitting and voltage.

When replacing your low voltage Halogen MR16 with an LED you might have to change your transformer. Most power supplies require a minimum of a 20 Watt load. Viribright’s MR16s use only 3.2 Watts of energy and the current transformer may not be able to run this low of a wattage. The current transformer should list the maximum and minimum load capabilities. For your safety, we recommend using an electrician to change out any electrical units.

    Will an MR16 with a GU5.3 base (12V ?) operate correctly if direct wired to a 12V battery such as an A23 or an automotive battery?

    Rod,

    Thank you for taking the time to inquire about a product. We do not recommend directly wiring any of our products into another power source outside the item manufacturing uses, specifications, or sockets.

    The short answer is yes. Directly wire a GU5.3 base, MR16 LED flood light bulb to a 12-Volt Battery, A23, or automotive battery; it will work, but we can not guarantee for how long, electrical failures, or even personal product safety. We recommend that if you use this light outside of its manufacturer’s uses, find an electrician or engineer who can give you a more direct and knowledgeable answer. We can only give you direct answers based on the product’s intended uses and not outside of those uses.

    Thank you,

    Team Viribright
