Q: How long does it take a Hybrid Light to fully charge?

A: Approximately 1 hr of good sunshine will give one hour of torch operation. So a full charge of 8 hours will provide approximately 8 hours of light. If charging on a cloudy day or from indoor artificial lamps, the time to achieve a full charge will be longer. If planning a trip away, we advise giving a full charge before hand (on a windowsill or balcony – even a dashboard as you drive around)

Q: Do the solar cells need replacement like batteries do?

A: The cells and charging system was made to last indefinitely. Unless cracked, you’ll be able to use it for years.

Q: How do you know when it is necessary to use the auxiliary battery (green LED) as opposed to just the stored solar energy (orange LED)?

A: You should avoid regularly using the back up batteries, and only switch over to them in an absolute emergency (long period of darkness such as when in a cave, or when the torch has not been recently charged). You’ll know when to do this as you initial flick on of the solar lamp (orange LED) provides no light; keep clicking the switch till the lamp comes on and the green LED illuminates.

Q: What battery type provides the backup energy source in the flashlights?

A: In addition to the main solar storage battery are 2 x Lithium CR2032, often called hobby batteries or large watch batteries. You should get ~50 hours of light from these when fresh, and these will have up to 6 years shelf life.

Q: How bright is the lamp

A: The EnergyDUO high intensity LED gives 40 lumens which is roughly equivalent to 1 watt of power or 16 standard LED’s

Q: How do you select the power source with the switch?

A: It’s simple to click between the two main power sources by just gently pushing in the button. The first click naturally uses power from the solar cells or the stored solar energy (orange LED, sunlight picture), and the second click takes you to the back up batteries (green LED with a battery picture).

Q: How do I know if the light is fully charged?

A: Whilst during charge the red light/LED indicator will glow, there is no indicator that the light is fully charged. 8 hours in the sun is best.

Q: Can it still charge on cloudy days?

A: Yes, but it is best to charge on sunny days when light is brightest.

Q: How heavy is the Solar Flashlight?

A: A measly, ‘pocketable’ 115 grams
