Just got three of these to replace the spot lamps in my kitchen light. So going from using 120w down to 21w....now that should save me some money on the electricity. They are shaped similar to the reflector bulbs but with a flat end and scrrew cap. They look really cool. As usual they take around 20-30 seconds to become real bright but the savings for your pocket and the environment is massive. £1.59 maybe high but for 10Yrs life and the reflectors only lasting around 2 years its a good saving all round. Not seem them any where else.
