Home Lighting Design For Aging Eyes – Part 2 – The Math

PROLOGUE

Please note that this is the second part of a two-part series on Home Lighting Design For Aging Eyes – this is about The Math, the earlier submission is about The Basics. [Hang on mathphobes, this stuff boils down to one number times another number equals a third number – like 2×6=12, like – like that you can take to a lighting professional who can deliver the illuminance goods.]

RECAP

In Part 1, we were presented with a unique set of rules and restrictions for home lighting design for aging eyes to two purposes. First, to achieve home lighting design standards more suitable to aging eyes (which the literature allows begin to need extra light in their 40s). Second, to translate these new home lighting design standards into numerical targets of common metrics readily identifiable in the retail lighting marketplace.

Common home lighting metrics include lpW (lumens/Watt) which illuminance efficiency data have been around quite a while and CRI and CCT lighting quality data which were hard come-by up until the last few years, as fluorescent makers “warmed up” their bulbs, and, particularly, their compact fluorescent lamps, or CFLs.

EXAMPLE

Comment: OK, let’s try on an example.

A bedroom has an ambient fc target value of 40, i.e., 40 lm/ft squared. That’s a given. The bedroom we’re targeting in this example is, say, 200 ft squared in floor surface area. 40 lm/ft squared multiplied by 200 ft squared = 800 l, our lumen target.

This house designer is not immediately, if at all, interested in that with which the space gets lighted (noting that method will be specified in the plan set, but rarely materials), except that it be lighted evenly and, by specific instruction, avoid lighting flutter from ceiling fan blades interrupting cast light. He’s not interested in specific luminaires (handled broadly in notes attendant to a lighting design schedule) by type, size, or, usually, specific site. Immediately, home lighting designer interest is in determining lumens for given spaces.

Eventually, choosing among materials and methods is for the knowledge of lighting pros and interior decorators and the personal sense of clients, etc.

Comment: Again, it’s the lumen number for a space coming from the Rules in Part 1-The Basics that bridges the gap between your lighting interests and intentions and the folks who know a lot about lighting but not a lot about you. At its easiest, bring your lighting professional The Basics and The Math – and the plan set.

NIGHTLIGHTING SCHEDULE

These calculations end up in a home lighting design Nightlighting Schedule defining by-level and by-space fc target, actual square feet, lm target, and distinction of task or ambient. Some spaces are necessarily scheduled in more than one line when, for example, task illuminance target varies from, say, shower to vanity – both for different target levels and square footage. Comment: It’s labeled “Nightlighting” to oppose it to a “Daylighting” Schedule of natural illumination to interior spaces – separate subject. Nightlighting and Daylighting can interrelate – yet, another subject in residential lighting design.

NIGHTLIGHTING NOTES

A home lighting design Nightlighting Schedule can be presented with extensive notes, including:
1. selected types of luminaires indicated, in order to keep perspective broad;
2. certain materials preferred, e.g., brilliant reflectors to get the maximum illuminance out of CFL downlighting;
3. rules of artificial, or mechanical, illuminance design repeated as a fall-back reference;
4. methods emphasized, e.g., layering, dimmers, under-cabinet skirting, etc.;
5. materials array is recapped, e.g., pendant, sconce, cove, etc.;
6. lighting quality hurdles indicated; site-specific concerns identified, e.g., about lighting potentially high-hazard spaces, possibly troublesome glare, cold-weather fluorescent materials and methods, safety-switching, continuous service rating, etc.

ELECTRICAL & LIGHTING PLAN

The home lighting design Nightlighting Schedule and related notes get translated in the Electrical & Lighting Plan in plan view.

This is not about beating a dead horse with texted table, extensive notes, and now a floor plan expression of wiring including lighting. This is about taking the wiggle-room out of residential lighting design and installation in application.

First, let the home designer define the lighting plan overall. Let the interior designing be done by designers guiding clients, based on the lighting plan. Then let the installation, the construction begin based on the interior designing and lighting pro’s instructions.

This custom home designer writes on the electrical plan space-by-space. He prescribes: foot candles by site, e.g., vanity, overall bath; distinction of foot candles by site by, i.e., task and ambient; switching and circuitry; and notes that, aside from specified heights and spreads of sconce luminaire, all aspects of luminaire materials and methods are done by others.

Before The Architect’s Ralph and Jean Pressel have worked together since the ‘60s on home designing, home plan drafting and repairing, home design and building consulting and on home building as contractors and subcontractors in every major trade. Electrical and Lighting Plans from their custom home designs shop are regarded as superior by clients, suppliers, and contractors.

LED Wall Lights Are the One Simple Purchase That Can Create a Mood and Design For Any Room

As far as indoor lighting is concerned, LED wall lights are a requirement for decorating the interiors of your house. Not only do they provide the customers with a vast range of options in designs and styles, but also function as flush-mounted lights which enhance the house from the inside.

The benefit of having LED wall lights is that you can install them very easily as it only involves fixing them firmly to the wall. Depending on the location of the installation, you can choose what kind of fitting you want and what additions you expect to be taken care of in your room.

The decorations differ from one room to another. Let’s take an example of a conventional living area; the wall lighting requirements here are going to be very different from that of a traditional dining room. In short, the LED wall lighting fittings are different for each room. However, it all comes down to your personal choice. So once you decide to purchase LED wall lights, it is advisable to go through the various images and photographs of wall lightings provided by the suppliers and manufacturers.

When it comes to lighting, the different wall fittings can make a lot of difference. By making some changes in the fittings using creative ideas you can influence the mood and appearance of any room. The perfect combination of appropriate light and design is what you need to make your room sparkling shiny.

Amongst the various kinds of wall lightings available in the market today, a wall washer is one fitting that is noticeable. What it does is that it highlights the furnishings hanging on the wall like paintings, etc. and also adds a sense of spaciousness to the room. By giving a false sense of bigger dimension, even the small rooms can be made to feel spacious.

Wall washers can also be fitted into ceilings in such a way that they would shine down on the walls that are in need of lighting. It is also possible to have them shine the room in the form of a wide beam that may be an upward or downward direction.

The LED wall lightings of today are more efficient and versatile than they were previously, and that is one change that you cannot expect from the traditional lightings like incandescent bulbs. In fact, it is not difficult to replace your regular wall fittings with LED wall lightings but it is still recommended to seek professional assistance when it comes to installation of electrical fittings.

However, if you have the basic knowledge of electrical outlets and wires, you can do the project yourself. Just make sure that you turn-off the power before touching anything and that you are well-acquainted with the wiring procedures.

Most LED wall lightings are influenced by local styles that can be found in your nearby store or in a catalogue or even a website related to interior decoration. Although they don’t come cheap, LED wall lights add a sense of coziness to the interiors of your home.

Improving Decor With Home Lighting

Beautiful contemporary home lightings add elegance to the décor of homes. New designs and fixtures of light bulbs and lightings are far superior in quality and looks than what we have been using in our homes in olden days.

Lighting brings warmth and makes home come alive. You can light rooms of your home with different types of suitable lights. Contemporary lighting highlights any room and makes it look the way we want.

Low level lighting or recessed lighting is one of the best illuminating sources. Its features of adjusting angles in different ways to lend designing effect to the room make it more popular for home lighting. It helps in illuminating dark areas in the room with adjustable uplift.

Contemporary home lightings include lamps which can be used in different special ways. Beautiful lamp designs can blend perfectly to give designer and cozy look to any room.

Lighting arrangement in any room is basically determined by its size and the usage for a specific purpose. A dining room or a study room has to be well lit in order to bring liveliness to the room. But for a bed room, which has to be cozy and warm for rest and sleep, you need dim, dull lighting. However your living room will require both types of home lightings; dimly lit living room to welcome guests and bright lighting for the evening entertainment.

It is now a trend in many homes to illuminate rooms with latest designer lamps. Rooms can be lit up with internally lit crystals, or LED lamps which produce raindrop effect in the living room as well as your bedroom.

New designs of lamps and lightings are environmental friendly; they enhance lighting effect with designer features and also save substantial electricity.
