1. What is CCT?
White LEDs are available in different Correlated Colour Temperatures, measured in degrees Kelvin [K].
The CCT communicates how much orange or how much blue is in the light emitted by the LED.
2700K-3000K values are orange-yellow in appearance, similar to sunlight at sunrise/sunset.
- AKA"warm white" they are easy on the eyes, and create relaxing atmospheres.
-This range closely mimics halogen/incandescent light sources.
5000K-6500K values are white-blue in appearance, similar to sunlight at noon.
"cool white" they are crisp, and create energetic, alert atmospheres.
This range closely mimics fluorescent light sources.
4000K values are pale yellow-white in appearance.
- AKA "natural white" they offer a balance of warmth and clarity.
2. What is CRI?
Colour Rendering Index is a measure of a light source’s ability to reveal the true colours of objects,
typically measured as a comparison against a ‘perfect’ light source, such as the sun which has a CRI of
100. In the early days of LEDs, typical CRI values were 60-70. Today, the industry standard is CRI 80.
apple Lighthouse supplies lights with CRI greater than 90 to ensure that your space looks great at reasonable prices.
3. Will I see the dots?
LED striplights consist of diodes/chips on a conductive ribbon. When these chips are far apart, you can
easily see their separation. This look can be unfavourable in high-end applications such as undercabinet
lighting and in-wall lighting.
To combat this, the striplight can be diffused with a lens; the farther the lens is from the chips, the
better it is at ‘hiding’ the dots. Even here, however, the dots can reappear when the light is dimmed, or
when it is reflected off of a countertop. In these cases, the best product for the job is a dotless strip
which uses hundreds of tiny LED chips spaced extremely close together and covered in a continuous
4. What do you have for undercabinet lighting?
apple Lighthouse carries different types of undercabinet LED lights to suit your needs, whether they’re
being installed in a kitchen that’s finished, or in a kitchen under construction. We would ask a few
questions to determine what would work best for you.
a. Do you like striplights or pucklights?
Striplights offer perfectly even light distribution onto the counter and backsplash. If you want every inch
of your counter brightened up, striplights are the way to go.
Pucklights offer a more dramatic effect by creating hot-spots on the counter and light-scallops on the
backsplash. You can use these hot-spots to accent objects such as flowers/art or features on your
b. Where are the power sources?
Dealing with electrical wiring is the biggest challenge with installing any kind of lighting system,
especially since every kitchen is different. We will discuss with you to determine wat you’re working
with, and what options are available.
5. Is it dimmable?
LEDs can come in dimmable and non-dimmable varieties. Nowadays, most LEDs for residential
applications are dimmable, but do require an LED-compatible dimmer. LEDs for commercial and
industrial applications are usually non-dimmable in order to save on costs, however, dimmable versions
6. What is an LED driver? How do I size it?
An LED driver is a power supply for LED operation.
- Potlights typically come with their own drivers; each light has its own driver. The electrician
would wire household power to each driver, so sizing is not required.
-Striplights and other low-voltage lights require separate drivers. Each driver can power multiple
lights, so it should be sized according to the need. The best rule of thumb is to never exceed
80% of the driver’s rated capacity.
o EX. You are looking to power 4 meters of a 12VDC striplight that consumes 10W/m; this
circuit would consume 40W. If you divide 40W by 80%, you would get 50W – this is the
smallest driver that you should use. If a 50W driver is not available, choose the next
available size up; in this case, it would be a 60W driver.
-NOTE: the driver voltage should always match the LED’s voltage. A higher driver
voltage will burn the LEDs, and a lower driver voltage will fail to operate the
