We all know that switching to LED’s is a safer and energy efficient solution but where do you start when choosing the right LED for you? Over the past several years there have been vast improvements with LED lighting throughout the entire industry but like all products there are important considerations when deciding to make a change so below are five handy tips to ponder when choosing the correct LED downlight for your home or office.

  1. Style – There are generally 2 types of LED’s on the market today; replacement globes and replacement fittings. A replacement fitting is a recessed style fitting including a new transformer and new globe. They have an opaque finish and cover quiet a large section of illumination. The other is a replacement globe, these can be replaced with your existing downlight heads and look very similar to a halogen light although much brighter and do not get as hot.

  2. Colour – Lighting colour is expressed in a number such as 3000K for warm white, 4000K for cool white and 6500K for day light, (K meaning Kelvin, a burn temperature of a globe which gives it its colour). In most cases, a standard home will use 3000K. Occasionally a cool white (4000K) will be installed in bathrooms and kitchens for brighter illumination. Offices tend to use 4000K also as it is a much brighter style of light but not to over powering. The 6500K is mainly used in entrances of buildings and food preparation establishments such as commercial kitchens.

  3. Beam Angle – A beam angle is how far the downlight shines outwards from the ceiling; the further out it is the greater surface of floor it will cover. Standard halogen downlights have a beam angle of about 40-60 degrees; they will illuminate an area of about 3meters in circumference depending on the ceiling height. Most LEDs however have beam angles between 50-100 degrees depending on the brand and style. LEDs can be quite useful if you are wanting to cover a large area or simply spot in one section such as a painting or sculpture.

  4. Brightness or lux level – A standard 50watt halogen globe has roughly the same lux level as a 7 watt LED globe therefore it is important to consider the wattage of the fitting so that the room you are looking to illuminate is not to dull. LED’s range from 10 – 15 watts. When choosing your wattage, it is important to note that different rooms and spaces demand a different level of lighting. A bathroom needs quite a lot of light compared to a lounge room where it is best to have a low level lighting. I suggest installing a brighter light fitting and installing a dimmer to operate the circuit to ensure you have just the right lux level all the time.

  5. Replacement Fitting Vs Replacement Globe – When replacing your halogen downlights to LED’s it is best to replace both the globe and the transformer as they both pose a risk of causing a fire. The majority of downlights on the market today have new transformers. The replacement globe is one such as the units being used in the government scheme, these are quiet simply changed over with the existing halogen globe; the transformer staying in the ceiling. Replacement globes are generally not as bright as they tend to have issues being powered by the old transformer.
