asked the Secretary of Trade and Industry what representations he has made to suitable firms in Great Britain about the desirability of manufacture of lightsticks, a cold light system based on the phenomenon of chemi-luminescence, in view of its use as a source of emergency lighting in explosive concentrations of gases or fumes and under water.

None. The specific meaning of the term "lightsticks" is not clear, but I understand that at least one manufacturer in Great Britain is already exploring the commercial viability of chemi-luminescent devices.
