![]() ![]() 10,000K: A very high CCT used in horticulture and aquarium applications.Instead, he recommends working within the Kelvin temperature range – correlated color temperature (CCT): 52:10 – 55:44: Color Changing LEDsīrian recommends not using color to attempt to enhance a feature. Typical applications would be to highlight flagstone, brick, or other rough surface material. Graze lighting reveals the surface and texture of any object. Place lights to the sides of the steps if possible. Try to light steps without cutting into them. Avoid placing them in turf – and if you must, make sure they’re protected. If installing these types of lights, place them strategically – at least 12 to 18 inches off the path – and/or protect them with objects such as boulders. Path lights are easily hit by extension cords, garden hoses, line trimmers, etc. Rule of thumb: Match the number of up-lights to the number of down-lights.ĭon’t do path lighting unless you absolutely have to. Use this technique on trees, translucent leaves, and open/airy plants. Use this technique on rocks, fountains, tree canopies, and multi-trunk trees. Minimizes textures (depending on placementīullet lights and well lights, pros and cons (40:50).Downplays dimension of plants and shrubs.Use this technique on houses, trees, shrubs, walls, pillars, and fences. Back-lighting: Establishes depth, shows little details, few shadows, lower light levels.Cross-lighting: Brings in shadows, adds texture, lower light level, enhances detail.Front-lighting: Eliminates shadows, minimizes texture, produces higher light levels, shows little detail.Trees and up-front lighting (front, cross, and back): Volt amps are used for sizing wire and transformers.Įxample of a spec sheet identifying volt amps (38:40)Ĭan’t find the volt amp spec? Multiply the watts by 1.5 39:45 – 52:09: Lighting Techniques.In general, keep wire runs below 200 feet.LED’s minimum operating voltage is 10 volts.It depends on the load and the size of the wire. What is the longest wire run I can have? (34:23) NEC rule: A transformer can only be loaded to 80 percent of its capacity. How do I know what size transformer I need?

Can you just pull the THHN type insulated, stranded wire instead of the UF cable? (21:40)Īnswer: Yes, you can. Question: I prefer conduit to direct burial. Zero cutoff refers to a horizontal plane through which light from an installation cannot pass.Įxamples of night lighting guidelines from (20:46) Ideally, fixtures should have a “zero cutoff”.Generally intended to reduce glare and light pollution.Often a product of an HOA or subcommittee.Of all codes, this one has the most variations.It’s manufacturers’ responsibility to make sure that their products are tested and up to date.Per NEC, all landscape lighting products must be “listed” with one of these agencies.All three are independent testing agencies that test products for safety.If you follow NEC, you should be covered.Will usually not be reviewed for permit.Trunk lines cannot have an amp rating smaller than the transformer unless that wire is fusedīrian recommends having a fuse installed that matches the load in the field for a lighting system.Wire needs to be buried a minimum of 6 inches deep and 24 inches deep under driveways and sidewalks. ![]() Wire can be direct burial wire (no conduit needed) as long as the wire is UF rated.Defines low voltage as lighting systems that do not exceed 30 volts.Covers the basics of installation rules.Guidelines for Laying Out a Lighting SystemĠ:00 – 5:00: Intro/TOC 5:01 – 29:14: Codes.You can also search for content on this page using the FIND command in your browser (CTRL + F in Windows, Command + F in Mac OS.) ![]() Note: The following catalog of content covered in this webinar is time stamped to allow you to follow along or skip to sections of the video that are relevant to your questions. ![]()
