LNK-LB-03B lifebuoy light is Intrinsically Safe light to be installed with lifebuoy. The light is SOLAS/MED approved and also certified for ATEX & IEC Ex.
The Marking is“   II 1G Ex ia op is IIC T4 Ga”-35℃≤Ta≤+85℃ which represents:
“II”=Group II Non-mining equipment use for applications other than mines.
“1”=Category 1 (Zone 012)
“Ex”=The equipment was fulfills current EN standard.
“ia”=Intrinsic safety with “very high” protection level.
“op is”=inherently safe optical radiation.
“IIC”= IIC goup explosive gas typical gas is hydrogen.
“T4”=The maximum surface temperature is 135℃.
“Ga”=equipment for explosive gas atmospheres having a “very high” Level of Protection which is not a source of ignition in normal operation during expected malfunctions or during rare malfunctions.
Ambient Temperature is -35℃ ~ +85℃.

It is a suitable lifesaving device for hazardous marine activity applications such as offshore drill platform, oil tanks etc.The light was designed with gravity sensor and water sensors double activation system. Once the lifebuoy light is thrown into water with lifebuoy, the head of LED lamp will automatically upwards owing to the gravity design, and the water sensors will contact water then activate the light immediately.If the head of LED lamp downwards or the light leaves from water, the light will automatically turn-off.
