Find My Bulb

Bulbs - FAQs

Here at Living Lights we are often asked about what type of bulb do I need for my home? Well look no further, our handy “find my bulb” tool will give you all the relevant information to make an informed choice on what bulb you need!

Whether its LED, incandescent, halogen, tungsten or otherwise we have a solution, remember to check the Frequently Asked Questions below:

Most LED bulbs aren’t dimmable as standard, so if you’re on a dimmer check to make sure the bulb you want is dimmable.

Standard G9 and G4 capsule lamps are very small in length, this can mean that the LED replacements are slightly longer, check your fitting to make sure there is enough room for the replacements.

Changing to LED will be sure to save you some pennies, most fittings have retro-fit bulb solutions where you can upgrade your fitting and make it more efficient, check our list below for you bulb.

LED retro-fit bulbs vary from one brand to another, our quality assured products are tested from 15,000 to 50,000 hours (depending on the type of fitting). LED’s are built to last a lot longer than any halogen, incandescent or fluorescent, but also they can save you up to 95% the energy consumption. So you will be saving money on your energy straight away!

Yes is the short answer, in a lot of cases LED’s use up to 95% less energy than most standard household fittings. The light emitting diode uses a lot less heat than its predecessors as its not heating a filament to create light, this saves a lot of wasted energy, and can also protect you if you accidently come into contact with a lit bulb (lamp).

Often this is more difficult and expensive than other fittings. Most fluorescents have a “Starter” and a “Ballast”, LED retro-fit bulbs don’t like these which can often blow the LED’s as soon as they are installed. For you to have someone come out, take apart your fitting, re-wire to bypass the ballast and starter so that you can buy the bulb itself can cost more than simply replacing the whole fitting. Our DR1101 and DR1102 round LED drum fittings are tested to 50,000 hours, they only use 8 watts and 18 watts of energy which can be found here. Our linear range of fittings are also a great solution, these can be found here.

Well, there are multiple things to consider, firstly is my fitting on a dimmer, if so that will narrow your search quite a lot already as most LED’s aren’t dimmable as standard. Also the size of the bulb is important, sometimes retro-fit LED’s are bigger than their predecessors so make sure you check this out before purchasing!

This is down to personal preference, often its advised that cool white is better for these rooms as they are a “cleaner” or “brighter” light, but this isn’t always what is best for you. If you have undercabinet lighting in your kitchen it is sometimes nice to have a warm white light to create a warmer more comfortable ambience. Also if it’s a kitchen dinner this can be preferred, or a mixture of warm white pendants with cool white downlights can create a nice look. For bathrooms again, much the same, warm white can be nice for a relaxing evening in the bath, while cool white is better for brushing your teeth, doing your hair or make-up. So it’s up to you!

Often they aren’t bright, they are used more as an effect and ambient light. Working beyond the colour of warm white, this can be nice to use as a backing light or side light when you want to relax. However always check the lumens as some of our amber bulbs can kick out almost the same light as their clear counterparts!

Check out the chart below showing you the different lumens and what they roughly equate to, the basic rule is 10% of the lumens would be the same as old fashioned wattage (E.G – 1000 lumens = 100 watts of incandescent light)
