On the other hand, HQL (metal halide lamps) lighting has Ra values closer to 100, making them better for aquariums that have lots of plants. A setback is that they cannot be used in smaller aquariums due to their high power output, so a tank of at least 40 gallons is needed. HQL lighting also can not be used with older aquariums, and they cannot be used in closed aquariums. An HQL system also requires a special setup needed to filter out UV rays. Lighting systems using metal halide lamps tend to be expensive.
Another significant use of solar lighting is in security systems for protecting private or government owned landscapes. This comes across as a low energy cost option for maintaining safety with security lights. These lights usually employ a motion detector to activate the light upon every movement in its range. Again, these solar security lights require no ground wiring, all it needs is the sun for getting the power.
The lighting fixtures used during the 1920s were traditionally finished with nickel and chrome. Not only do these metals add a touch of sophistication to the bathroom, but they also make the space really bright, as well. Nickel and chrome are reflective materials that bounce the light off their surface and around the room. You may make use of frosted glass and chrome combination lighting fixtures for added elegance.
