We make tailored modules for technical or architectual lighting.
Standard we make reflectors in aluminum housing which can work on mains or DC low voltge sources.
PL24 is linear reflector and example on pictures is from underwater installation we made tailored reflectors to fit existing installation.
All reflectors works on 24V.

PL24 is special designed that each line which is 12 meters long has own 1W LED with lens 5°.
Thanks to good cooling performances lamp can work without water and housing do not exceed 30°, in water this is much better. 
This working condiditon will give long working life to reflektor.

This is picture without water where we performed 24 hour test.
