Smart management of hotel properties consists of many different aspects, and one of those is lighting. When it comes to ambience and comfort, lighting plays a critical role in setting the tone for your guests. LED lighting makes a sustainable contribution to your businesses bottom line, ecologically, esthetically and economically.
Energy savings is one important factor, but the advantages go far beyond that for the hospitality industry. The Color Rendering Index and Kelvin Temperature are especially important factors. LED lighting can play an important role by presenting the right color and the right amount of light for any restaurant or hotel application. The Color Rendering Index (CRI), numerically measures the ability of a light source to reproduce the colors of various objects in comparison to natural light of the sun, which has a CRI of 100. So a luminaire with a CRI rating of 92 shows more colors than a Luminaire with a CRI rating of 82. Kelvin temperature measures the hue of light, the whiter the light the higher the kelvin temperature.
So why are CRI and Kelvin important?
Color Rendering Index and Kelvin Temperature seem like complicated ideas to understand but they’re not, and they can make a big impact. Since LED lights are solid state devices, they are infinitely programmable and hold their color even when dimmed. Colors hold their true color even under lower light conditions. LED lights have a very high color rendering indexes compared to traditional lighting sources and they provide superior light quality and acuity for workers and guests. LED lighting is exceptional for outdoor use. The higher amount of white light and high color rendering index allows for better parking lot security and clearer images when using surveillance cameras.
Examples of light color and hue
For example 5,700K is the color of daylight, which is a white light and sunrise is 3000K, a warm light. Since LED Lights are infinitely adjustable and come in a wide variety of hues, it’s easy to pick the right LED solution for your application. A modern restaurant or hotel would look best using a LED luminaire or lamp with a higher Kelvin Temperature of 4,000K to 5,000K. A more traditional restaurant would look for a LED luminaire or lamp with a color temperature of 3,200K, which has a warmer look to accentuate the wood and earth tones.
The hospitality industry is one of the sectors with the largest energy savings potential. Lighting is one of the most impactful ways to reduce energy costs. 42% of energy usage comes from lighting, most of which, is inefficient.
Typical applications include:
- Parking lot lights
- Main lobby and Hallways
- Hotel Rooms
- Leisure areas – including pools and exercise and entertainment rooms
Most restaurants operate a minimum of 16 hours * 365 days a year. For franchise operations, the savings for switching to LED are staggering.
Typical applications include:
- Outside canopy lights
- Indoor architectural and droplights
- BOH lighting
For a typical restaurant that uses 60W incandescent or 75W Halogen lights consider the following example for savings. The example will use a $.10/kWh as a base and 5840 hours for the year.
|Existing Fixture and Wattage||Total KWH||Annual Power Cost|
|16 Outside Canopy 75W Hallogen||7008||$700.8|
|75 Indoor 60W Incandescent||26280||$2628.00|
|Maintenance – bulbs/ballast/labor||30%||$998.64|
|Proposed LED Solution||Total KWH||Annual Power Cost|
|16 Par 30 18W LED||1681.92||$168.2|
|75 E26 LED 8W||3504||$350.4|
|Maintenance -5yr warranty||0||$0|
