Fluorescent lighting has been around a long time and you may not think it is that efficient. Old fluorescent lighting certainly isn't T12 and T8 tubes and their drivers can be horribly wasteful, sometimes using double the amount of power they are rated at. However T5 fluorescent tubes coupled with a modern ballast is remarkably efficient, almost as efficient in fact as LED lighting. Modern warm start ballasts have also increased reliability and allowed for extending the life of the tubes which can now reach as much as 30,000 or 40,000 hours. Modern drivers also operate at high frequency, unlike their older counterparts, which mean there is no longer a noticeable flicker with fluorescent lights. Fluorescent lights do also suffer from early failures, and because they rely on a filament the more often they are turned on and off the shorter their life will be; this means turning them on and of with presence detection to reduce their use and save money on your bill could backfire when you have to frequently replace the tubes. If you do go down this route make sure the drivers feature warm start and don't set the controls to frequently turn the lights on and off.
The dominating advantages of LED over the conventional lighting like; incandescent bulb and CFL, makes them the best choice for every new installation and upgrade that needs to be illuminated. LED converts 80% of your electrical energy into light energy. So it does really justify for what you pay off. This ultimately reduces your expense on electricity bill and thus, saves both energy and money. For example, replacing old lighting system with new LED system on Iconic Miami Tower helped to save $259,767 annually in energy, maintenance and operating costs.
Some applications for landscape lighting include the use of small floodlights whose beams can be adjusted to showcase shrubs and trees or the side of a house. Walkway lamps provide downlight for safe passage to a house along a sidewalk or path. Blooming flowers, shrubs, fountains and pools can be showcased with landscape lighting and there are low wattage bulbs available in a variety of colors as well, for dramatic effects.
