In 12V LED systems, the transformer and power supply are located away from the LEDs, typically in a cool and vented area. Typically, capacitors will fail and cause the LED bulb to begin blinking. In many cases, premature LED bulb failures are not caused by a failure of the LED chips themselves, but the electronics that are located inside. For many products, these electronics components must be condensed and mounted onto a small circuitboard that is in turn placed inside of the bulb, where temperatures can soar due to the heat emitted by the LEDs. 12V LED systems are more reliable, and can be repaired and serviced.In addition to the LED chips, a line voltage LED product must also contain complex electronics such as capacitors that convert AC line voltage into DC so that it can be used by the LEDs. For reference, the UL standard for low voltage lighting systems (2106) is limited to systems that carry less than X watts in total. Similarly, fire safety is related to the total amount of energy involved - even at low voltages high amounts of current can easily create a fire hazard. Optical safety is dependent on the intensity and wavelength of light emitted by the LED - something that is independent of the LED system voltage.
One caveat is that 12V LED systems do not have any significantly lower optical or fire safety risk. To pass these certifications, products must meet a stringent set of safety rules that include rules about minimum wire spacing and insulation. For example, high voltage systems will almost always require UL or ETL testing to be approved for sale in the United States and Canada.
Generally, if you accidentally create a short circuit, you will not see any sparks or loud bangs that you would see with line voltage systems.īecause of the general safety advantage of 12V LED systems, product design can be simplified as well. This makes it safer for hobbyists who want to experiment with products such as LED strips.
12 VOLT LED PANEL LIGHTS SKIN
Because 12V is a much lower voltage compared to line voltage (120/240V), it is more difficult for the electrical current to overcome the built-in resistance of human skin and other objects. 12V LED systems have a lower electric shock risk.When it comes to LED product safety, optical, shock and fire risk are often considered. This makes power supplies readily and cheaply available and can help reduce your purchase costs. 12V is a very common voltage level primarily due to its common use in desktop computing. On the other hand, even if you are not going to be using batteries, you will still need to rely on power supply units. Many batteries for vehicles including boats and RVs operate on 12V DC, which makes using a 12V LED system a no-brainer for these applications, as there is no need for any additional transformers or power supplies to convert the voltage - your LED lights can be plugged in directly.
Many electrical systems operate on 12V DC, and you are probably already familiar with several of these. A 12V DC LED system is a common voltage platform. Before you move forward with that purchase, see below for our list of advantages and disadvantages for a 12V LED system! Top 3 advantages of a 12V LED system 1. If you've been shopping around for an LED strip or other LED product for RVs and vehicles, you are likely aware that these products do not run on line voltage (120/240 V AC) and instead, you will see 12V DC as a common option.
