How bright is a 60-watt LED bulb?
An LED that uses 60 watts is in no way comparable to an incandescent bulb that uses 60 watts. In fact, a 60-watt LED just may blind you. LEDs are designed to use less energy and naturally have a lower watt rating. This means it's useless to use watts to determine brightness.

Lounge areas requiring low level ambient levels of light either use a dimmer to adjust the output or widen the distance between fixtures to 5ft-6ft (1.5m-1.8m) and therefore use less.
Do lighting manufacturers give instructions?
When you purchase almost anything the supplier would usually give you instructions on how to use it. Interestingly lighting manufacturers do not, as there are too many variables to consider to accurately advise properly. So we must advance with caution in the knowledge that these calculations are a crude guide and rely on downlights only to achieve a blanket covering of light and do not consider other circuits of light.
Is a downlight easy to install?
However, the downlight’s strength of being so effective, discrete and easy to install can also be its weakness as they are over relied upon, used incorrectly and potentially can spoil your lighting scheme. There is way more to learning about their spacing’s than just distance.

Keep in mind that halogen downlights reach temperatures ...
Do IC rated downlights require a transformer?
IC Rated modular downlights do not require a transformer/driver as they are connected directly to a power supply. Therefore replacing halogen downlights with IC Rated modular downlights will save additional energy that would otherwise be consumed in the transformer/driver (i.e. between 1 and 15 watts each). Installing IC Rated modular downlights also removes another potential source of failure in the supply chain as the transformers/drivers will eventually fail over time and require an electrician to replace it.

These holes will allow a very small volume of air to circulate because this is what they are designed to do. Some LED downlights do not require ventilation holes such as the new Ecomatters lamps we are now installing.
How much less energy does an LED downlight use?
As you can see, LED downlights offer a much more energy-efficient solution and use up to 90% less energy. When compared with fluorescent lighting, LED downlights consume around half the energy, with a 12-watt LED downlight capable of providing the same brightness (or lumens) as a 24-watt fluorescent bulb.
How do LED downlight wattages compare to halogen and fluorescent downlights?
Typically, standard halogen lights have a wattage of around 55 watts, while LED equivalents range from 4.5 watts to 14 watts.
What are lumens?
Lumens are now used as a more accurate measurement of brightness, and watts to gauge energy consumption. Modern LED downlights are designed to use less energy and therefore have lower wattages, making them much more energy-efficient while providing more light output.
Why do you need LED downlights?
In addition, an LED downlight will usually last longer than a halogen downlight, reducing the need to keep buying and changing replacement bulbs.
What is wattage in light bulbs?
While most people still associate wattage with the amount of light you expect to get from a bulb, watts are actually a measurement of how much power goes into the bulb, not how bright it is .
What is lumen rating?
Lumens are a measure of the amount of visible light emitted by a light source. The higher the lumen rating, the brighter the light will be. LED lighting offers much brighter lighting, using much less power because less energy is lost through the heat of the bulb.
Can LED downlights be adjusted?
Most recessed ceiling downlights also allow you to adjust the beam angle as required, allowing you to achieve the perfect light in any environment. Adjusting the beam angle of your LED downlights allows you to focus light in the areas you need or want it or for more focused task lighting.
