These lamps are equipped with an over-temperature protection (OTP) which causes the lamps to automatically switch off prior to overheating (especially when operated at extreme environmental conditions) and therefore prevents damage to the lamp. Thus, the product life span is significantly increased. The life span of the lamp is more than 8,000 hours.
Fits in any standard light socket, so it's very easy to convert your favorite lamp to 12 Volt DC for solar energy systems.
