A customer who is remodeling a historic building in the French Quarter asked for Design services for lighting. The switching plan for this space was very important so as to NOT destroy the look of the spaces with switches and dimmers all over the place. After completing the layout the designer added cabinets in the bathroom which would best be lit and worked with the electrician to create 5 gang switch look in the master water closet. This wasn't necessary. A simple email to the designer and owner adjusted this. While this seems simple support, the reason you use a lighting supplier that handles layouts is because switching/dimming becomes an afterthought for many, but not for the experienced lighting and controls designer. The learning here is to NOT make switching/dimming an afterthough. Put as much effort into this part of the plan as the lighting and furniture layout.
At PEMBA the simpliest things are important. Here is the email feedback from the customer. " Patricia, As recommended I am moving the WC under cabinet switches to mirror wall near the outlet. I am also having another outlet placed to the right of the door and into the WC (more convenient for my hairdryer). Sid and I are working thru things..... thanks for all your expertise, your products and your amazing skill and patience!"

We hear about LED lighting that fails and in addition to surges taking care when doing maintenance is important to prevent the early loss of life of LED bulbs. To help keep those LED lights working, I am copying the paragraphs below from an email received by Kevin Smith of BrillianceLED.
"Back in the halogen and incandescent days of landscape lighting, it was a common practice by many contractors to install lamps while the system was on. This is known as a “hot plug-in”. This practice has been widely used especially if a contractor was out providing maintenance on a lighting system.
As we have evolved into the era of LED light sources, the practice of hot plugging should be avoided. The reason for this is that it is virtually impossible to be 100% sure that there will not be the slightest electrical arc when a lamp is inserted into a socket or a connection is made with live cable. A hot plug-in can cause an “electrical over stress” (EOS) on many parts of the internal circuitry of an LED lamp or integrated fixture.
EOS can simply be described as an electrical component that is operated beyond its maximum rated electrical limit accidently or deliberately according to its rating on the specification sheet. In landscape lighting EOS can occur with a hot plug-in, a lighting strike, or a poorly made connection.
Some common signs of EOS are as follows:
• One or more diodes out; in this case, the bonding wires inside the LED device have been broken.
• Another sign could be a pungent burnt smell emitted from the lamp.
• In some cases the back of the lamp may show a burn hole, especially with lightning.
EOS can also have an adverse effect on a fixture that requires a remote low voltage driver. If a driver is connected live when attached to its respective fixture, it can cause an EOS failure.
The question now is how do we change the hot plug-in install? My suggestion would be that when performing maintenance on an older system, unplug the transformer before installing the LED lamp or integrated fixture to insure the power is off to the socket. This same method can also be used on new installations with a standard landscape lighting transformer. If you happen to be working with a smart app driven transformer, insure the remote control has the system off. Most of the smart phone apps will allow for a simple on and off for the transformer.
Ultimately, to avoid EOS, make sure to have solid potted cable connections and no power to the fixtures upon installation. If a situation arises where lightning has caused the EOS, check to see if the homeowner’s insurance will cover lightning damages."

Regularly a customer tells me that they do not have enough light in their kitchen. One of the problems that I regularly find is that the bulbs that are being used are BR type bulbs which not necessairly for task lighting. Many times these same customers have PAR type bulbs in their liviing room. After having them put the higher lumen PAR bulbs (850+ lumens) in their kitchen they see a big improvement. So using the right light bulb, does make a big difference in your kitchen. We have a variety of light bulbs on display in our showroom at 104 P Street in Belle Chasse LA . Stop by so we can help you select the best lighting for your home or office. Patricia Smith

Designing and Recommending the right lighting has become a passion of mine. Ever since I was asked to take that lighting control course many many years ago I have been on a quest to apply the appropriate lighting. I am starting this blog because there is so much that is mis understood about selecting and placing lights and you don't know when you have bad lighting unless you have experienced good lighting. So for today I am going to just mention a few fundamental statements that I'll address in future posts.
1) brightness requirements of light varies with time of day, by person, and by environment and task.
2) placement of light should be designed when discussing use of space.
3) there are multiple colors of white.
4) The ultimate goal in lighting is to NOT see the light fixture unless it adds a decorative value.
We test lighting products and display them in our show room and I work on a variety of projects. So I'll be posting something soon!
