LED 2D & Double D Bulbs

Typically used in interior or exterior bulkheads, Double D or 2D lights often use CFL energy-saving lamps for operation. While fluorescent lighting is substantially more energy-efficient than incandescent, it holds no such advantages over LED. LED double D bulbs will cut your energy usage by at least half over a CFL equivalent, in addition to boasting phenomenally long lifespans - typically 15,000 to 30,000 hours.

There are other advantages, particularly relevant for the likely use of this lamp: with LED you get instantaneous light without flickering or warm-up time; a particularly rugged, solid state form of lighting, LED is very well suited to utility lights that might be subjected to a bit of disturbance; LED is eco-friendly and easily disposable, whereas regular energy-savers use mercury and require special disposal.

You might also find our double D fittings incorporate a movement sensor, so you can fit the lamp readily into an appropriate light fitting and it’ll switch on and off when it senses anybody present. Unlike a CFL lamp, this potential to switch on and off doesn’t place any undue strain on the LED light or disproportionately lessen its lifespan.

Cut energy-usage by half and give your bulkheads a bit of a breather - buy LED double D bulbs!
