  • We think the 4w led bulb is one of the most beautifully crafted and expertly designed led bulbs currently in the UK market. Keeping the functionaltiy of existing high-consumption bulbs whilst combining the numerous benefits of LED technology. Whether you're installing or replacing existing, you will save energy, lower electricity bills, save money and help the environment. There are 20 epistar brand 5050SMD LEDS on each bulb creating a delicate yet powerful light, colour temperature warm or pure white optional, without the bulbs getting hot to touch and without the need for constanting replacing them. The benefits to you and the environment far outweigh the initial expense.
  • Please note: There MR16 bulbs have a 12v input and require a lighting transformer, however we strongly recommend an LED driver transformer for maximum performance especially when dimming.

What Dimmer Switch for LED light bulbs?


We've all read about it, we've all heard about it. Dimming LED (light emitting diode) bulbs can sometimes be a nightmare. Flickering, strobing, buzzing and just switching off all together when you dim them down. Just have a quick glance at this page and see if we can point you in the right direction.

LED light bulbs are great. They have an incredible lifespan, they don't get hot to the touch, they consume far less energy than your incandescent equivalents and now you can also get the dimmable alternatives. However, those brilliant energy-saving qualities mean that you have to be slightly more selective when it comes to choosing an appropriate dimmer switch.


Adjusting the voltage to halogen bulbs will provide a large smooth dimming range. LED light bulbs are not like halogens, as there wattage is very low when in comparison. A problem is therefore created, as the majority of dimmer switches operate with relatively high loads (25-250w for example). And if your combined wattage of LED light bulbs is below the minimum wattage for the dimmer switch to operate, it will not operate correctly. And simply having a large number of LED light bulbs with a high combined wattage, all working off one dimmer switch, may not guarantee success either unfortunately. We strongly recommend using a trailing edge dimmer, and they may even be advertised as 'LED dimmer switches'.


Trailing-edge Dimmer Switches

They can operate at lower wattages, they have a soft start for extended bulb life, step-down under partial overload, switch off under gross overload, have smooth control, are silent-running and are multi-way dimming.
