Helios T5 Gold has been developed for industries where a very low actinic radiation (<500nm) is needed e.g. semi-conductor industry cleanrooms, wine storage cellars - Helios is an entirely new class of linear LED light source with exceptionally high system performance, - Outstanding operative efficacy , - Omnidirectional 360degree radiation - More uniform surface luminance, - Consistent lumen output and colour temperature, - Hermetically closed tubes, - no escape of silicone vapour from LED's which can disrupt industrial processes, - No entry of sulphur or other LED damaging gases, - Remote driver allows full dimming and controllability, - Can tolerate high ambient temperatures >50 degrees Celsius
