The new LED lamps produce a superior quality of light compared to many earlier solar products available to rural off-grid users. Using a typical Correlated Color Temperature (CCT) of 4000K, the new lights deliver a balanced white/yellow light which is warmer on the colour spectrum, creating illumination that is more restful on the eye and reduces the potential for sleep disruption compared to cooler, white-blue light.
The lamps deliver a typical conversion efficiency of 147 lumens/watt and operate at low voltage, which is important when powering from a battery, ensuring maximum light output from a given battery charge. This, coupled with Azuri’s fully digitally-controlled solar home system designs, allows for a precisely controlled shine for the duration of use.
Part of the innovation of Azuri’s home solar system is its pay-as-you-go model, where top-up credit is bought on a weekly basis to allow payment for the system to be spread over a period of 12 to 18 months. Accordingly, the lamps have been designed to be robust and durable, providing optimal output for at least 15,000 hours, or 2,500 days based on 6 hours of use each night, to ensure that each solar home system can continue to provide free, clean light to the consumer long after they have completed payment.
