Introducing Keystone's 360° LED Sign Tubes! The Sign Hero series from Keystone is the perfect solution for retrofits or new sign installations. There is no need for an external driver or ballast, making it the fastest way to upgrade a sign to LED, while still using the existing sockets. Maintenance professionals can install these LED sign tubes in five minutes or less! The Keystone Sign Hero LED Sign Tubes are an LED outdoor replacement retrofit solution for conventional T12HO and T8HO fluorescent lamps for sign applications and come in the color temperature of either 4000K or 6500K. These LED tubes can cut your energy savings nearly in half!
Talk about an easy retrofit option for your existing fluorescent T12HO or T8HO sign bulbs. The Keystone LED Sign Tubes feature a rotatable R17d base for correct lamp orientation in vertical or horizontal installations, regardless of how the socket was originally installed. This tube is two-sided so it can light up single sided or double sided signs. The optical lenses that cover each individual LED chip in the tube eliminates hot spots and ensures a consistent light distribution across both face of the sign. You will no longer get those awkward vertical shadows. You can count on Keystone to provide a 50,000 hour lifetime and a 5 year warranty. The heavy duty aluminum heatsink does ensure that the LEDs will run cooler for a longer period of time, while the plastic and aluminum construction ensures less breakage.
