Hotenda LED 4 foot replacement bulb is great for updating those outdated inefficient tubes. Simply eliminate the ballast, and wire the bulb to a single end. Non-shunted lamp holders (or tombstones) are required. Consume half the energy and still get the same light output.
* Ballast/starter of existing fixtures must be bypassed or removed.
* Lamp holders or tombstones must of the the non-shunted type.
* Power is to be applied on one end of the bulb only (labeled). One live and one neutral pin (powered end) and two pins for support on other end. Specifications

120LM/W Ultra Bright: EPISTAR Chip ,High efficient output, single-ended power, High-grade PC cover with nice light transmittance (>95%), 2200 lumens ultrahigh brightness
0 light decay(@5000h): Use the high quality aluminum PCB for LED's better heat dissipation,Use the most mature international well-known LED SMD2835 as the light source, which can ensure the led tube brightness and long lifetime, also can reduce the light decay
CRI>85: High color rendering of light source to reproduce the color is better.No flickering ,no startup delay, also energy saving more than 60% than conventional lamp
Easy Installation: Direct replacement of fluorescent 40w T8 tube,No ballast required,wide voltage AC85-265V and constant current design
5Years Waranty: 35000 hours long life.
