2.Battery powered lighting one of the favorite picks for most art showrooms for this does not need any type of wires and hence it is easy to mount and use while adding the best nuances to your painting or picture. This is also a superb choice for travelling artists.
Through the ages man has been fascinated by fire since its discovery. Man attempted to harness the power of flame to provide both heat and light. As knowledge about fire evolved, fire became portable. Used to light the interior of caves and dark natural passageways in dense woods, portable fire was both dangerous and unpredictable.
Once the design and type of outdoor lighting fixture is selected, the next important question is voltage. Outdoor light fixtures are available in either 12-volt or 120-volt versions and for houses the best deal is low voltage outdoor lighting. These are easier to install as the system runs on harmless 12-volt current with light weight wiring laid on the ground or buried just below surface. The 120-volt system on other hand is same as used in interior of house and requires precautions and handling. The advantage of high voltage outdoor lighting is that it is permanent using buried conduit whereas the low voltage outdoor lighting is that is easily damaged due to superficial placement of wires.
1. The LED color rendering index used is too low, causing the emitted light to not reflect the true color of the object. (Light source on the object's color rendering capacity known as color, color rendering index Ra up to 100, the best color) The current LED color rendering index of 80-85, then, has been very good, can be used indoor lighting.
