From EiKO Global, we have high-quality T5 linear fluorescent lamps. They are designed for low electricity consumption and superior performance. End pins are crimped for heat resistance and reliability, and these fluorescent tubes are available in 49 watt or 54 watt models with a range of color temperatures. There's warm white 3000K and 3500K, 4100K cool white, 5000K daylight and 6500K full spectrum lamps. These energy-efficient, budget-friendly T5 lamps come in bulk quantities of 25 lamps for an even greater value. Other features of these high output fluorescent lamps include a color rendering index (CRI) of 85 and programmed start. They're rated for 35,000 hours of bulb life. The less frequent need for re-lamping greatly reduces maintenance costs.
