Very hot operating temperature Cool running 20 - 40ºC
2000 – 2500 hrs lifespan 30 000 – 50 000 hrs lifespan
Economical calculations:
Using a 25W halogen capsule (G4) over the lifespan period of 30.000 hours consumes 7500KWh energy worth of £90.00 (based on electricity cost of 12p/KWh), while using a 1.8W, 9 SMD LED G4 light consumes only 54KWh energy worth of £6.48.
The overall saving, based on a 30.000 hours lifespan and electricity cost of 12p/KWh, is £ 83.52 on each light, which you can achieve simply by replacing your conventional lighting with LED lighting.
