Provides light for 33 minutes. Same amount of light as Utevo Lux. Unlit it looks the same as an Old Power Core. Can be refilled with a Vial of Oil. Important Note: you must use the lamp on the vial in order to refill it. If you use the vial on the lamp you lose the oil and the lamp is not refilled. It is not known why it does not refill the other way around.
