The new Philips CorePro LED HID SON T lamps are a simple LED solution with a fast payback for replacing High Intensity Discharge (HID) lamps. This new generation of products offers all the energy efficiency and longevity benefits of LED for HID replacement while providing immediate savings with a low initial investment. They also have the same size and light distribution as other HID lamps, so you won't notice the difference. All this thanks to our HighPower LED filament technology. Their unique IP65 design also allows them to be used for outdoor applications.
