Production Description:

<p> <strong>4FT T8 LED Tube with Emergency Battery Backup Power </strong>is an all-in-one general purpose lighting and battery powered emergency backup TLED solution. The tube acts as a normal lamp, providing high lm/w and supporting on/off switching operation and dimming. Upon loss of power, the batteries provide a minimum of 90 minutes of light, starting at half of the rated light and decreasing slowly over time. The standard input end powers the lamp in normal mode, and the emergency input end charges the batteries and senses the presence of AC power.&nbsp; </p> <p> <span style="font-size:18px;">FEATURE</span> </p> <p> <span style="font-size:14px;">Built-in Lithium battery and driver</span> </p> <p> <span style="font-size:14px;">Both mains supply and battery supply operation LED Emergency lighting<br /> </span> </p> <p> <span style="font-size:14px;">Fire-resistant, high temperature resistant, thermal-insulation, anti-climate aging probongs tubes lifetime.</span> </p> <p> <span style="font-size:14px;">140 minutes at 3w by battery supply in emergency;</span> </p> <p> <span style="font-size:14px;">Lithium battery: longer lifetime, over 500 times charging- discharging</span> </p> <p> <span style="font-size:14px;">2 years warranty</span> </p> <p> <span style="font-size:14px;">Life time: &gt;30000hours</span> </p> <p> <span style="font-size:14px;"> <table style=";" cellspacing="0" cellpadding="2" bordercolor="#000000" border="1"> <tbody> <tr> <td> Index<br /> </td> <td> LED Tube 600mm<br /> </td> <td> LED Tube 1200mm<br /> </td> </tr> <tr> <td> Power<br /> </td> <td> 9w<br /> </td> <td> 18w<br /> </td> </tr> <tr> <td> LED Type<br /> </td> <td> 2835 SMD<br /> </td> <td> 2835 SMD<br /> </td> </tr> <tr> <td> Input Voltage<br /> </td> <td> 85-265vac<br /> </td> <td> 85-265vac<br /> </td> </tr> <tr> <td> Light decay<br /> </td> <td> &lt;15% at 10,000 hours<br /> </td> <td> <span style="font-size:14px;">&lt;15% at 10,000 hours</span><br /> </td> </tr> <tr> <td> Beam angle<br /> </td> <td> 120°<br /> </td> <td> <span style="font-size:14px;">120°</span><br /> </td> </tr> <tr> <td> CRI&nbsp;&nbsp;&nbsp;&nbsp;<br /> </td> <td> 70<br /> </td> <td> 70<br /> </td> </tr> <tr> <td> Working temperature<br /> </td> <td> -20℃~50℃<br /> </td> <td> <span style="font-size:14px;">-20℃~50℃</span><br /> </td> </tr> <tr> <td> Emergency time<br /> </td> <td> 140 minutes<br /> </td> <td> <span style="font-size:14px;">140 minutes</span><br /> </td> </tr> <tr> <td> Emergency Power<br /> </td> <td> 3w<br /> </td> <td> 3w<br /> </td> </tr> <tr> <td> Battery capacity&nbsp;&nbsp;&nbsp;&nbsp;<br /> </td> <td> Lithium 2000mAh&nbsp;&nbsp;&nbsp;&nbsp;<br /> </td> <td> <span style="font-size:14px;"><span style="font-size:14px;">Lithium</span> 2000mAh&nbsp;&nbsp;&nbsp; </span><br /> </td> </tr> <tr> <td> Charging time<br /> </td> <td> 6 hours<br /> </td> <td> 6 hours<br /> </td> </tr> <tr> <td> Reflector / Diffuser<br /> </td> <td> Frosted diffuser<br /> </td> <td> <span style="font-size:14px;">Frosted diffuser</span><br /> </td> </tr> </tbody> </table> Function Description</span><span style="font-size:14px;"><span style="font-size:18px;"></span></span><span></span> </p> <p> <span style="font-size:14px;">The <strong>emergency LED T8 tube light</strong> can converses automatically between normal lighting and emergency lighting. if there is no mains supply. the battery will be in operation.
