Coloured lenses can really enhance the appearance of plants, trees and garden ornaments. Dichroic glass filters operate on a passive-reflective basis, reflecting unused wavelengths while passing wanted portions of the spectrum. They are high in transmission which results in brighter, cleaner, saturated colours, compared to that of a standard plastic lens with colour films which often fade. Their low cost and easy replacement makes experimentation with different colours an interesting prospect at an affordable price. Simply place between the 50mm MR16 / GU10 lamp and exterior glass lens of the fitting, secure with a spring clip and you have a coloured lamp. Change the coloured lens periodically to create eye catching and unique effects; a colour for every season.
