Highly engineered, the SunBlaster NanoTech T5 Reflector is super lightweight and made of high-grade heat proof PVC. The reflector simply slides into the T5 base housing and snaps on, installing between the lamp and the base, maximizing your T5HO lighting recovery, output and performance. The heat reflection extends both lamp and ballast life. The NanoTech T5 Reflectors' placement captures 100% of previously wasted light, reflecting no less than 99% of it back into the growing area as high-quality diffused light. This diffused light provides deeper and wider canopy penetration for better starts and accelerated growth cycles.
