New 12w LED Driver Transformer for MR16- MR11- G4 LEDLight Bulb Zero Interference with Dab and WiFi Energy Class A++

Product Information

You can now get dimmable G4’s in 220VAC & 12VDC. This asks the question… is its best to swap the driver and use 12V LED’s or by-pass the original transformer and use 220V LED’s? Different LED drivers are required for different environments for example indoor, outdoor use or kitchen or bathroom. If the driver is to be used outside we recommend that a waterproof driver is used with a minimim IP 65 rating. We would also recomend this for kitchens and bathrooms a waterproof driver with a IP67 minimum rating is used. Beauty Advent calendars are significantly pricier than chocolate ones, but they've become increasingly popular in the last few years as a way of bagging beauty products at a fraction of the normal cost. They often sell out early, but can also be heavily discounted later if they don't, so here's a round-up of some of the best I’ve seen.

LED drivers' are electronic DC power regulators designed specifically for DC LED lighting. They are not suitable for 12VAC (halogen or LED retrofit) lighting. Spotlights are ‘directional’ bulbs that emit light in a focused beam. Halogen spotlights are a form of incandescent light bulb that use a tungsten filament and a mix of inert and halogen gases to produce light. The European Commission directive in September 2016 banned the manufacture of this type of power-hungry spotlights. The LEDs are too far from the transformer, resulting in voltage drop (the maximum distance is about 1.5-2m).

How far away should I house the LED transformer?

transformers output a high frequency switching signal ranging from approximately 37 kHz to 79 kHz, enveloped All mains powered LED bulbs require a transformer. Depending on the bulb type, the transformer/driver may be built in to the bulb casing or may be located externally. The purpose of the transformer is to reduce mains voltage (240V) to the desired level relative to the bulb being powered (e.g. 12V or 24V). Switching to LED - which bulbs require a transformer? MR16 LED light bulbs will function with the majority of standard low voltage MR16 LED drivers however some are typically 20~60VA which can cause problems for this lamp due to the transformer minimum load requirements not being met. Compared to halogen bulbs the LED MR16 bulbs draw a significantly smaller amount of power, therefore do not provide a sufficient load for the more traditional Halogen low wattage MR16 transformers. The ~ sign indicates alternating current. Also, the minimum load is indicated as 10W. This is important when using LEDs

Driver should refer to a current regulated DC power supply, but often same name given to voltage regulated device, so you need to be careful.This is personal preference. Some customers like to have one transformer per fitting or light strip so they can deal with any potential faults easily. It may not always be possible to use one transformer per fitting due to constraints such as space and cost, so keep this in mind when buying. However, many prefer to use one transformer to power a series of bulbs or light strips (maximum five metres on one transformer). As explained above, the transformer you require to do this depends on the combined wattage of the bulbs you’re powering. GU, which stands for “general use”, refers to the base, or fitting, of the bulb. The number after GU refers to the spacing between the pins. GU10 has 10 mm spacing, while GU5.3 has 5.3 mm spacing. MR16 and GU10 bulbs are both technically MR16 bulbs. One has a GU10 type base and the other has a GU5.3 type base. The bulb with a GU5.3 base has simply become known as an “MR16 bulb.” The bulb with a GU10 base is commonly referred to as exactly that: “a GU10”. Here, we’ll refer to the two bulbs as MR16 and GU10.

The volt-ampere (VA) rating is the maximum load (in watts) that a transformer can safely carry. For example, a 40VA transformer can handle up to 40-watts of electrical equipment, while a 10-60VA one can carry between 10 and 60 watts worth. Installing low voltage LED light bulbs on a transformer designed for halogen lighting requires you to find the equivalent wattage ( see above) for the LED bulbs, so as not to overload the transformer.DPO2012B oscilloscope.
