Local building control authorities determine the amount of time that a ceiling can hold back the fire, thus the term fire-rated ceilings. Typical fire rating for a ceiling is an hour and the best ones can last up to two hours. Cutting a hole in a ceiling to fit downlights will compromise the ceilings fire rating. Because downlights are not designed to fit seamlessly into a ceiling, the gaps formed within the light fitting will now be the ceilings weakest point where flames and smoke can pour through and spread the fire to the floor above. Ideally, each luminaire in a downlight fitting should be fitted with a fire protection cover which prevents both flames and heat being transmitted through the luminair up into a ceiling gap.
Solar garden lighting is another cost-effective way to bring light to your flowering garden. Solar lights use a single battery composed of Nicam (nickel and cadmium) which is charged throughout the day by sunlight. At dusk, solar garden lights automatically turn on and at dawn, they automatically turn off. Again, solar garden lighting is available in a variety of sizes, shapes and colors. Colorful stings of lanterns, butterflies, stars, hummingbirds, and many other shapes can be found easily. Also solar statues, stakes, rocks and poles can be used to illuminate garden pathways.
Take a string of fiber optic lights to highlight the curve of a garden pathway, the edge of a pond, illuminate the tiers of a waterfall, dress up a tree trunk or branches, or outline the frame of your garden umbrella.
