d.Light D30

The d.Light D30 is comprised of a 9 Wp Polycrystalline silicon solar panel, a 3000 mAh, 6.4 V Lithium-iron phosphate battery and solar controller, 3 LED lamps with wall switches (upgradeable to four lamps) and a USB port for charging mobile phones.

Also included are a rechargeable portable torch (with 1500 mAh, 3.7 V battery), a rechargeable solar FM radio (1000 mAh, 3.7 V battery) and a universal USB adaptor for mobile phone charging.

The individual lamps each emit 120 lm of white light in a wide distribution on their high brightness setting and the torch emits 75 lm of white light in a narrow distribution on its high brightness setting.

The battery and solar controller unit shows the credit remaining based on current Pay-as-you-go payments and current battery level on an LCD screen.

Products within the 2 year warranty period (from the date of purchase) can be returned to the retailer at a user’s point of purchase for replacement free of charge. Beyond that, d.Light provide customer support (contact details available here).

Prior to discontinuing this product, the manufacturer listed the lifetime as “over 5 years” for the D30 on their webpage.

Lighting Global confirmed that the d.Light D30 complies (verification document) with the Lighting Global Quality Standards by testing according to the Quality Test Method given in edition 3 of IEC/TS 62257-9-5. The results can be found here and certification is valid until May 31, 2020.

The testing categories (all passed) are: Truth In Advertising; Lumen Maintenance; Battery Composition; Battery Protection; Battery Durability; Physical Ingress Protection; Water Ingress Protection; Drop Test; Soldering and Electronics Workmanship; Mechanical Durability; Minimum Warranty Terms; Performance Reporting.

As specific testing of the lighting elements of the system:

A full day’s charging with the 9 Wp polycrystalline silicon module will provide enough stored energy in the battery to power the three lamps on a high brightness setting for 5.6 hours and the torch on high brightness setting for 3 hours, resulting in a total light output of 360 lumens and 75 lumens, respectively.

Total lightning service for this product is 2200 lumen-hours/solar-day for the four lightning points with high-brightness setting. Regarding lumen maintenance, after 2,000 hours run time, 97% of the lamps’ original output remains and 94% of the torch’s original output remains.

This Solar Home System is a plug and play device, however, electrical installation and control guidelines provided by d.Light must be followed to avoid electrical shocks.
