TerraLUX’s LED lamp for use in low-voltage track lighting integrates with true 35W or 50W halogen equivalence and is compatible with existing low-voltage transformers and phase dimmers. There are three replaceable lenses and four user-selectable light output levels that can be managed by a pushbutton on the side of the unit. Light levels range from spot beam, narrow flood, flood and wide flood, with light output at 430 or 640 lumens in four color temperatures.
