Description

Perfect for the LUMiLiFE range

The LED Transformer / Driver is used to power low voltage (12v) LED bulbs and strip lighting. LED bulbs require a constant voltage to work properly. Sometimes a normal 12v transformer will work correctly with LED bulbs, but in some cases the lifespan of the bulb will be reduced.

Dimmer compatible

This driver allows dimming of constant voltage LED products using conventional TRIAC dimmer switches such as trailing edge or leading edge which in the majority of cases means you don't have to have replace your dimmer switches. LED lighting does require Trailing Edge technology in order to dim. Please contact us if you’re unsure on your dimmer switch compatibility.

What transformer do I need?

You need a transformer that can power the total wattage of the strip or bulbs being used. For example, if you plan have 2x 5W MR16 LED bulbs that total 10W, you would be recommended a 20W transformer. 20% of the transformer capacity needs to be left over to prevent overloading. Please contact us for advice or assistance if unsure how to proceed.

3 year LUMiLiFE warranty

On selected LUMiLiFE products, we offer an automatic 3 year warranty. This entitles you to unlimited replacements from the original purchase throughout the warranty period. If your original purchase is no longer available, a new replacement with the latest equivalent model will be offered.

Lumen

Since LED light bulbs are designed to use less energy than halogen spots, wattage is not a reliable way to gauge how bright the bulb is. Brightness is measured in Lumens.

With LED spotlights there is more to consider than just a direct Lumen comparison with the halogen equivalent. The superior light quality given off by LEDs and much lower bulb degradation rate over time must also be taken into account. This is why the stated Lumen output for an LED spotlight is often less than that quoted for a halogen spot bulb it replaces.

Beam Angle°

The beam angle is how wide the beam is spread. If you have a very narrow beam angle your light will be projected like a handheld torch whereas if you have a wide beam angle it will be much softer and spread like a traditional bulb. Wide beam angle are best for living areas such as living rooms, dining rooms and bedrooms where you are looking for a softer light and narrow beam angles for targeting specific areas or for decoration.

Power Consumption (W)

The wattage is the value given to the energy consumed by the light bulb itself. So, a 50-watt halogen spotlight bulb will use 50 watts of power. If you have 6 x 50-watt halogen spots in your kitchen then you will be using 300 watts of power. If you were using replacement LED lights at 4 watts each you would be using 24 watts of power, resulting in huge energy savings.

Input Voltage

This is a measurement of the volts required to operate the bulb. The standard for the UK is 240 volts. This means that you can plug these directly into existing fittings without changing any of the electrics.

Height (mm)

The size determines the diameter and the length of the bulb. In most cases the bulbs are a retro-fit, which means they are a direct replacement for their halogen equivalent.

Width (mm)

The size determines the diameter and the length of the bulb. In most cases the bulbs are a retro-fit, which means they are a direct replacement for their halogen equivalent.

Depth (mm)

The size determines the diameter and the length of the bulb. In most cases the bulbs are a retro-fit, which means they are a direct replacement for their halogen equivalent.

Wattage Replacement

This details what this LED bulb is a replacement for in terms of standard halogen bulb wattage. This allows you to easily make a comparison when replacing your existing halogen bulb, to ensure you get a similar light quality and brightness from your new LED bulb

Average Life in Hrs

Manufacturers will give lifetime claims in multiples of 1000 hours. One thousand hours is equivalent to about 6-months use when the bulb is on for 4 hours per day. A traditional halogen spotlight bulb is expected to last about one year (2000 hours) where as an LED will last between 30,000 and 50,000 hours - that’s between 15 and 25 years! Switching to LEDs means you may never have to change your light bulbs again.

Base Type

This is the fitting of the bulb, described by a letter/number code. You can find out what your fitting is by looking on the base of the bulb you are replacing or the packaging of your existing bulb.

Dimmable

Dimmable LED bulbs are only compatible with a dedicated "Trailing Edge" dimmer switch that reduces the current flow. Your bulbs will not work effectively if used with the conventional "Leading Edge" dimmer switches that operate with a higher current flow.

When ordering dimmable LEDs please ensure you have an LED-compatible Dimmer Switch.

Protection Rating

The IP rating is an international classification system for the sealing effectiveness of enclosures of electrical equipment against the intrusion into the equipment of foreign bodies (i.e. tools, dust, fingers) and moisture. IP65 for example, is dust tight and water resistant.

Colour Rendering Index (CRI)

Measured on a scale from 0 to 100 percent, the colour rendering index (CRI) indicates a bulb's ability to make reds, greens, and all other shades look just the way they should. Simply put, the higher the CRI, the more accurate an object's colour would look under the light source.

Warranty

We're so confident in the quality of our bulbs that we offer an extended 3 Year warranty

A useful driver that is constant voltage but still dimmable. Not easy to find at a sensible price.

This was used to replace an existing failed transformer that was driving a dimmable LED in one of our 200 serviced apartments... Probably didn't need expensive 20w one but wanted to replace like with like since what was there has lasted well (in 5 years this is the first one of 16 to fail)

Work very well with dimmable mr16 leds ( used on groups of 4 with 3w led mr16s )

Looks a good product. However, it would be useful to have more output terminals - one pair compared to a similar low voltage transformer with three pairs

I use this dimmer with the LED strip. It does not dim to zero - only about 50% but it is useful when I want ambient rather than working light. Excellent quality - nothing flimsy - and terminals clearly marked

Work well with correctly derated load. Flickered with 15w load (25% derated) am now advised to derate by 50% so am replacing with TRAN-30D.

Neat, well-made product, that was a simple replacement for the old halogen transformer. Easy DIY job, provided you switch off the mains first! And of course assuming the old transformer is reasonably accessible. WHole swap, including crawling around attic, took about 10 mins

Needed to know the % loading figure in order to decide on the correct model to order and this wasn't available on the product info so I didn't know it mattered. We have a constant flicker on the lights.
