Guest room lighting at the hotel

These photographs will show you the effect of lighting scene to the hospitality industry, specially for the hotel guest-room application. Simple & smart solution to make guest enjoy room more, to make them more relaxed, build their mood or perhaps helping guest feel like in their own room at home. Guest will easily set the lighting scene with control button that placed near their bed.

To avoid the “discotique” effect caused by too many lighting color applied, the hotel management (or perhaps lighting designer) carefully selected the lighting color for each room. The lighting intensity also can be controlled by dimming system, so it will not too bright or too dark, and all of effect will be controlled by Guest himself/herself, because they are the owner of this room 🙂

Solar Panel installation mistakes

To get the most from solar panels, you need to point them in the direction that captures the most sun. Solar panels should always face true south if you are in the northern hemisphere, or true north if you are in the southern hemisphere. True north is not the same as magnetic north. If you are using a compass to orient your panels, you need to correct for the difference, which varies from place to place.

For solar panels to cost-effectively generate electricity for their owners, the panels need solar exposure between about 9 a.m. and 3 p.m. Owner has to make sure that there are no obstacles that reduce the capability of solar panel to catch the light or solar. Not all outdoor area is good for solar panels. There may be trees that cast too much shade on your parking area or street, for example. So please make sure that solar panel has enough solar to catch or produce become electricity and avoid mistakes happened from images below.

Flexible wall illumination

With flexible wall illumination you can change the color and the mood of your shop, creating the right ambience for a given audience at a given time. The color can change very gradually or within a second. It can change over a period of time (e.g. to attract attention) or it can remain static for as long as you want it to (e.g. to complement a promotion). It can change between bright, saturated colors and soft pastel tones of white, e.g. to create a warm atmosphere during the winter.

Make the customer stay longer

Flexible and adaptive, lighting enables retailers to create dynamic shop environments that convey powerful, engaging impressions. It can be used to optimize product presentations, and it can be adapted to support the latest‚collection, specific themes, the seasons, materials, colors, etc. It can also create a stage for temporary promotions.

Make the customer come back

In the evening too, when the shop is closed and outside lighting levels are low, new dramatic effects can be applied, again creating fresh and memorable impressions.

Decorative elements on shop lighting


Case study:

Color-changing LED to highlight the product-display. Maybe the purpose of installing color-changing effect will give good appearance and attracting people to give more attention to the product-display. But it is not correct. Why? Because it can’t reveal the true color of products that display. The Blue color of clothes will not display as blue, the white color of shoes will not displayed as white, etc. Color-changing effect will work when the surrounding area set to dark, and if the surrounding area more bright, the color-changing LED will meaningless.

Solution :

Decorative elements can be applied throughout the shop. They can be used for a variety of purposes, for example to attract attention and create stopping power – highlighting product presentations and visual merchandizing, complementing retail promotions or the shop interior, or creating ambience for a given occasion or audience. The lighting color can change very gradually or within a second. It can change over a period of time or remain static for as long as you want it to. Decorative elements can also be used to underline architectural details, for example to enhance your store’s brand image.



The lighting in a shop is a key factor in creating that all-important first impression. Dynamic decorative elements attract attention of people passing by and enhance the in-store ambience. And lighting scenes that change within a short space of time are even more eye-catching because people are very sensitive to changes in light.

Marker/Path Lighting

Decorative Lighting for building, especially for outdoor area can be realized in many applications. One method is using path lighting that placed on the ground. The lighting system and cable buried under the ground. But in some application, people seems make wrong choice for solution. Instead using lighting system that dedicated or designed for path lighting, they use spot lighting. It will illuminate the area and make discomfort for human eyes. It will create glare.

From the photograph below, the luminaire/housing is right, but the lamp is wrong. Also it using Halogen lamp. This lamp type has short lifetime, high wattage consumption and create heat. So be careful on make product selection.

What is a LED?

LED is stand for Light Emitting Diode. It means semiconductor (diode) that can produce visible light. Sometimes LED called as Solid State Lighting, because it made from solid form or material. On conventional lighting, light produce by gas that ignited by filament on closed tube or glass. That’s why conventional lighting must be taken care carefully on packaging, delivery and installation because it’s fragile.

  • A semiconductor device that converts electrical energy directly into  discrete color of light
  • Made from different materials and substrates
  • Made in chip fabrication factories
  • No brass, glass and gas (“solid state”)
  • White LED Sources are a blue LED device + phosphor
