G4 Led Bulb 12v Ac For Landscape Lighting

Must read

W G4 Led Capsule 12v Ac/dc

G4 dimmable 2w 12v LED Bulb with G4 Dual Pin Base

This 12v G4 LED bulb is one of the most effective lamps available to date. It is available in Warm and Daylight White and has an impressive 200 lumens output. G4 LED capsules are a great replacement for halogen bulbs, they produce less heat, have a longer life expectancy and are more energy efficient. This G4 LED bulb consists of a silicone body which protects the LEDs inside. This is especially useful when used with lights where there is no external protection for the bulb.

These versatile 12v LED G4 bulbs work on a 12v A/C transformer or a DC transformer with no need for any special drivers. They are therefore ideal for use in long cable runs.

All Transformers Have A Wattage Range For Close Consideration

If you have a transformer previously used with halogen bulbs and you are looking to change these to LED, the likelihood is that the transformer will be too large for the system, expecting a higher amount of current to be running through the system. LEDs use up to 90% less power than halogens. Therefore a lower wattage transformer should be used so as not to underload the transformer. If a transformer is underloaded, it produces a higher voltage output, and may cause the LED bulbs to flicker or fail prematurely. Under normal circumstances, it is expected that only the circuit in question will be tripped. If any further lights in the household were to blow, we would advise a second professional opinion in case there is an issue with the electrical wiring.


How To Identify Your Bi

Not sure what kind of mini indicator lamp you have in your fixture? No problem. There are a few simple steps you can take to figure it out. Step one is to identify the type of base. These bulbs have a straight bi-pin base, meaning there are two pins that extend straight out from the bottom of the bulb. Since there are several different bi-pin bases, including G4, G8, or G9, the next step will be to measure the pin spacing. The number after the “G” represents the space between the pins in millimeters. So, G4 bi-pin bulbs have 4 millimeters, or .157 inches, between the pins. The next thing you need to know is the voltage used in the fixture. The approved voltage rating should be printed somewhere on the fixture housing or socket. Failing that, a voltage rating may be printed on the bulb. Once you have your replacement bulb, installation for G4 bi-pin is as simple as pushing it into the socket.

Replacing Existing 12v Halogen Bulbs To Leds

All 12v systems require a transformer in order to convert the 230v mains supply to only 12 volts the required voltage for low voltage light bulbs such as G4s, MR11s and MR16s . With the amount of money and energy LEDs can save a household, along with their long lifespan, many people are replacing their existing halogen bulbs with LED equivalents. However, there are a couple of things to consider. Here is what you need to know

There are two different types of transformers: magnetic and electronic. Old style magnetic or wire wound transformers, are fairly simple, using coiled wires around an iron core to convert the power to 12v output. All Lumena transformers work in this way. Electronic transformers have more complications, with some older types produced prior to LED bulbs, uncompatible with LEDs. The electronics of the transformer tend to interfere with the electronics of the LED bulbs, thus causing flashing, flickering or even no light output at all. Newer electronic transformers are generally designed to power LEDs, and therefore work well, as long as the wattage and current type are also correct.

Some LED bulbs will only work with 12v DC power supply. These need a 12v DC transformer or they will not work correctly, if at all. Some LED bulbs, such as Lumenas LED G4s, MR11s and MR16s run off of both 12v AC and 12v DC. Either an AC or DC 12v transformer will work, causing no issues at all.
