Many houses, shops and displays use small spot lights to illuminate and look fashionable. Up until quite recently, these were almost all halogen spot lights. With the development of LED (Light Emitting Diode) lights, all the most common spot lights are now available as low energy bulbs. It is easy to replace the old halogen bulbs with new energy efficient LED bulbs.

Is it worth changing the bulb from halogen to LED? Let’s take a look

	Halogen	LED
Light emitted (luminous flux)	500 lm	500 lm
Power consumption	50 W	5 W
Cost to buy	£1 – £2	£3 – £5
Life	2000 hours	20 000 hours
Annual Running Cost (if on for 2 hours per day)	£9	£0.90
Expected Life (if on for 2 hours per day)	2.7 years	27 years

Break-even will occur within a few months. So well worth making the change today.
