Note ＊ :

Letter S at the end of a lamp code indicates a lamp is made of a synthetic fused quartz. The intensity of 184.9nm line is more than twice of the same lamp made from a normal fused quartz glass.

Note ＊＊：

The pencil shape low pressure lamp: Black Light Eastern Corp．/Americ

The Spectral Radiant Energy of a lamp“11SC-1” is the relative value compared to the value of the 253.7nm line
