Compatible with BOTH our standard on/off switch and upgraded dimmer cable option.. This is a fantastic upgrade to any of our salt lamps which offers the following benefits over our standard 15W incandescent bulb:. Brighter light: The 6W LED that we offer is brighter than the standard 15W incandescent, we use these LEDs in our office and they are absolutely wonderful and really make the lamps glow.. Lower energy consumption: LED Bulbs use up to 90% less energy than an incandescent or halogen bulb of equivalent brightness. LEDs are far more efficient at converting electricity, measured in watts, into light, measured in lumens.. Better for the environment: A well-built LED with good thermal management should last up to 50,000 hours. This means they are less likely to need to be replaced over their lifetime and less waste.. Money saved: By switching to LED, a considerable amount of money can be saved due to the lower wattages of the products. LEDs also last far longer so you won’t need to replace them often and their reliability means you won’t need to worry about maintenance.
