Lighting Lingo – How We Measure Light

• • • • • • • • • • • • • • •

Efficacy- Energy shown in lumens per watt (lpw) Lumen- Intl Measurement for visible, spherical light LPW- Lumens per Watt- Lumens output divided by consumed watts Foot Candles- Measures light on a surface Foot Candle- One foot candle equals one lumen per sq. foot Candle Power- Measure light in a specific direction Lux- European- Shown as 10x Foot Candle Kelvin Temperatures- Colors of the spectrum Watts- Measures heat; not light output Lumen Maintenance/ Dep.- the degree in which LPW is maintained CRI- Color Rendering Index (1-100). Intl for light quality Lamp Delineation- MR, R, PAR, A, E12, E27, T, G and GU Lamp Design- Measured in 1/8 of an inch (ex; MR16) Watts to Lumens- Approx. 10-14 x factor (avg.) LED Measurements- In the past LEDs were point source and not spherical in design. Today we can measure LPW (L/W), Lumens and Foot candles (light falling on a surface).

Lighting Lingo- Glossary of Common Terms

• • • • • • • • • • • • • • • •

Amps / Amperage- The “engine”- Measures the flow of electricity through a wire Volts- The “speed and acceleration”- Measures the pressure through a wire Watts- The “amount of fuel used”- Measures the energy consumed (MPG) Circuit- An “electrical branch” off the main power supply Resistance- Electrical pressure on the wire impairing the flow of electricity Voltage Drop- Percentage of diminished voltage Photo-metrics- A measure of a fixtures actual light output at various distances Lamps- The technical term for a light bulb Beam Spread- A degree of width at the farthest measurement on a directional lamp Ohms Law- V x A = Watts Multi Tap- A power source that has the ability to accommodate several voltages Arc-ing- A electrical fault where the current is unstable- usually from a loose connection Home Run- A loop from a wire back to the power supply AC- Alternating Current. Normally used in “daisy chain” wiring DC- Direct Current. Electricity flows in one direction. Normally used in battery technology and LED electronics Series vs. Parallel Wiring- Series are wired together and Parallel are separated. With Parallel, if one light goes out the others stay on. With Series wiring, one light will affect the whole chain.

Basics of Lighting Design – How to Prepare?

•What to light? Critical overview of property •What are customers requirements, likes and dislikes •What is the objective (safety, security, beauty, energy efficiency, etc.) •What are the important areas of the property •Look for competing light sources (street, house, neighbor) •Determine the effects that will be important •Harmonize and consider natural elements •Accentuate key elements of the property •Determine electrical load that is available •Determine zones for proper wiring •A little light goes along way in dark environments •It’s all about the lamp •Determine what to light •Determine light levels and requirements •Types of Colors (Kelvin) •Ambient Lighting- below 40 lpw •General Lighting- 40-50 lpw •Task Lighting- 50-70 lpw

Lighting Design - Planning Check List

• • • • • • • • • • •

Overview of the property- features, boundaries and key elements of interest View the property at night- identify safety and other elements that are hidden in darkness How much light will be required? Interview and listen to the property owners Decide on a theme or concept: natural, entertainment, festive, subtle, romantic, color, etc. Paint and frame with illumination: Accentuate key elements and focal points Offer various illumination levels- “stage” light with effect. Use light level contrast for impact. Compliment other lighting- interior, house lighting, neighborhood Consider the budget- Type, quantity and material of fixture, Switching requirements- Determine what is best- timer, photo cell, motion or remote control Future growth of the landscape- Plan for the future. Allow enough cable and power. Maintenance- Think of re-lamping and servicing of the fixture.

Landscape Lighting Installation- Planning by Zone

• • • • • • • • •

Stage the property into “zones”. This will be helpful for wiring, power supplies and maintenance. Determine the zone by transformer and access to electricity How many fixtures in the zone? How many watts in the zone? Design for proper and consistent voltage Size for the appropriate transformer Size the appropriate cable Determine wiring method- daisy, loop, T or hub Flagging the zones

Note: Lamps are measured in 1/8’s Ex:MR16 = 2” (16 divided by 8)

What fixture/lamp for what application cont. Average size tree at 10 ft • 10w – 20w MR16 Average size tree at 20 ft • 20w – 35w MR16 Average size palm tree at 30 ft • 35w- 50w MR16 Walls, Shrubs, Walkways and Landscape Areas • 20w or 35w T3 Stairs and Steps 10w-20w T3 or Single Contact Bayonet Large Trees • 35w- 50w PAR36 or MR16 Notes: The more narrow the beam angle the greater the lumens. Beam angles change geometrically as distance increases Lenses, Louvers, Frosting and Coatings all affect the beam angle Light bounces off of reflected materials (trees)- so a wider angle may not affect the object being illuminated.

Landscape Wire and Cable

Cable size and type is critical to a successful installation Wire size is basically the number of copper strands. Just like water through a pipe, the flow is critical. • • • • •

Stranded Cable vs. Solid Cable (120v or 12v)12v current runs through stranded cable while 120v current runs on the outside of the cable 12v Wire Sizes- Largest to Smallest 8/2, 10/2, 12/2, 14/2, 18/2 Wire Chart Shows the difference in cable properties- strands, load, size Burying the Wire We recommend PVC sleeve to protect the cable Wire Connections We recommend gel filled wire nuts or grease tubes to keep moisture from the copper contacts.

Voltage Drop and Consistent and Equal Voltage

•

Voltage drop definition The degree in which voltage is diminished affecting lamp performance. A standard 12v lamp requires a consistent 11.0v to 12v for a successful installation.

•

Voltage drop can be overcome in several ways: # of Fixtures Size of Cable Wattage Load Multi Tap Transformer

Note: LED is fast becoming the better alternative as LEDs have a lot more flexibility at 9v – 14v range. - Less worry about voltage at the first light - Less worry about finger oils - Less worry about voltage control

Voltage Affect on Lamps

Consider that lamp life is rated on averages of 50%. This means half of the production life will last longer and half of the production life will last shorter. • • • • • • •

13v= 131% Output = 35% of rated life 12.5v= 120% Output = 67% Rated life 12.0v= Mean Base Line 11.6v= 93% Output = 200% Rated Life 11.0v= 75% Output = 300% Rated Life 10.5v= 65% Output = 500% Rated Life 10.0v= 50% Output = 900% Rated Life

Pop Corn Effect: As lamps begin to expire, voltage/current will rise and affect current, resistance and voltage. This condition is problematic with 12v-22v multi-tap power supplies and daisy chain wiring methods.

Wiring Methods

•

Daisy Chain- Wiring from one fixture to the next. Positive: Easy install Negative: Voltage drop and voltage consistency

•

Looping- Running a wire from the last light back to the transformer Positive: Easy with no thinking Negative: Does not address voltage at the first few lights

•

T or Hub- Running a cable to a centralized zone and then tapping off to fixtures A Hub is basically a T within a direct burial splice containment Positive: Equalizes voltage and removes the error of over exposure at the first few lights Negative: Uses more wire

Best and Recommended: T or Hub in zones Daisy Chain with LED in zones

Power Supplies / Transformers •

A transformer is essentially an electrical device that “transforms” or steps down higher voltage to lower voltage (typically 120v to 12v).

•

A transformer is made of copper windings which slows down the speed of electrical current.

•

Transformers are available in a variety of wattages, voltages, materials, protection and accessory options.

•

Landscape transformers are typically 120v / 12v AC.

•

The transformer is the heart of a good landscape lighting installation.

• •

A good transformer has the following features: Made of non-ferrous materials, has multiple voltage options, primary and secondary protection and options for timers, photo cells and remote control switching.

• •

A multi-tap transformer offers incredible solutions to compensate for voltage drop. 12-15 volt or 12-22v

Tools of the Trade

Tools of the trade- What you need on the truck. • • • • • • • • • • •

Amp probe- Test the primary voltage first (110-130v) Digital Voltage meter Continuity tester Wire cutter / stripper No oxidation grease Gel filled connectors Shovel, Spade and Trowel Color flags Electrical tape Zip ties Fixture load and wiring diagram for future maintenance

Important: • Use di-electric, no ox or lithium grease on all connections! • Make sure all connections are tight!

Custom Mounting Options and Long Term Success- It’s all in the details.

• • • • • • •

Determine weather changes throughout the year Determine upcoming landscape changes Standard ground stakes Permanent posts Risers Surface mounts Tree mounts

Estimating Lighting Projects

A 12v installation still requires a review of available 110v. The load factor on the GFI outlet requires enough amperage to accommodate any new lighting installation.

• • • • • • • •

Determine total electrical load (wattage) required Determine electrical access and availability Determine the # of fixtures Determine the quantity of cable required Consider wire runs and access from power supply Determine standard halogen design or LED installation On average- one experienced installer can put in 25 fixtures per day KISS- We recommend a unit price cost per fixture which includes ALL materials

Cost and Profit

Profit Margins – It’s in the details! Cost of Fixture Cost of Wire Cost of Power Supplies Cost of Lamps Cost of Connections Cost of Labor How to Select Fixtures When to Scale Up When to Scale Down Tricks of the Trade A typical installation can earn a profit of $1,000.00 per day.

Note: Many contractors include the total price of the project into the cost of the fixture. For example, an estimate may say that each fixture is $200.00 to simplify the proposal. This represents all costs associated with the installation, including labor.

Sales and Presentation

Finding and closing projects is as important as any other tool. Your marketing materials are critical unless all of your business in word of mouth. Clients are typically visual.

The sale will be much easier if the client can visualize what they are going to receive. Lighting projects are easier than other installations as demo kits will provide the sample taste to generate interest. • • • • • • • • •

Marketing and lead generation Net working, web site, door hangers, direct marketing Setting up the client meeting The importance of image and pictures The importance of branding Letters of recommendation Web Site Factory Endorsement and Warranties Demo Kits

Calculating Energy Costs -a topic for every lighting proposal

Most clients are very concerned about cost of their electricity Watts is energy consumed no matter what technology

• • •

Total Watts x Hours of Use x KWH rate (.15) Divide by 1000 Equals Cost of Electricity

• • •

Example: 1000 watts (total fixtures) x 10 hours per day divided by 1000 x .15 x 365 days in use = $547.50 annual cost

• • • • • •

Understanding Tier-ed RatesTake a look at your electric billBase Rate- Initial rate for electricity Delivery Rate- Cost of Delivery to Property Tier Rate- Starts and base line and increases with usage levels Note: There is no average on a KWH rate

Why LED?

•

A discussion of energy costs will usually lead to the hot topic of LED. This technology creates a great “buzz” and most clients are extremely interested in low energy products.

• • • • • • • • •

Easier Installation Less Cable Lower Transformer Wattage and Cost Longer Life 9v to 14v Voltage Range Less Voltage Drop Less Worry About First Fixture Voltage Greater Color Options Solar Compatible

New Technology- LED

Led is the most efficient light source available Led lamps last 30,000 hours (avg.) Led lamps operate with virtually no heat or affect to room temperature Led lamps offer tremendous energy savings Led lamps are shock and vibration resistant Led lamps do not produce UV and are safe for art and textiles Led lamps offer vibrant color options Led lamps are the basis for new solar technology LED lamps have a lumen maintenance ratio of 70%, which simply means that they hold performance LED lamps are now available in most standard bases and sizes LED lamps can now be mixed with AC and DC power LED lamps in a retro fit form are preferred as LED’s continue to improve every year LED lamps not only saves electricity but also reduce cable, transformer and maintenance costs

LED Basics

• • • • • • • • • • • • •

Identify the need for LED vs. other lamp options Consider the fixtures and environment Understand that LED fundamentals are constantly changing Use only replaceable or service-able LEDs Stay away from old technology (5mm and low power chips) Watch for extremes in voltage fluctuations Don’t lock yourself in. Make sure you have options in the future Consider Kelvin colors. Customers are very picky about color pallet Same fundamentals as a low voltage systems The new LED’s are now compatible with AC power (DC technology) T Method or Hub Method recommended Can be mixed with standard 12v Voltage Drop Formula and Amp Ratings- See Load Info

Solar LED - The Next Frontier

Stand Alone Solar Power is gaining in popularity but had limitations that were hard to overcome… until now. To create enough power to accommodate a 300 watt + system required a large and expensive solar panel. With low energy LEDS the wattage requirement is dramatically reduced, allowing smaller and less expensive independent solar power generation. What is Solar Power? • Stand Alone Portable Solar vs. Grid Solar? • What is a Solar “transformer” • Why LED Solar • Benefits of Solar • Overview or Solar Hybrid Power Transformer • • • •
