•LED modules and illumination units may vary in illumination colors and illuminance
*1) LED life depends on the operating environment. Ta = ambient temperature
*2) Waterproof and oil-proof characteristics guaranteed for conditions specied by IEC60529 (IP67),
JIS C 0920 (IP67F/IP67G), and DIN40050-9 (IP69K).
*3) IP67F: LF1D-C/H/J, LF1D/LF2D-EN, LF1D/LF2D-FH (reinforced glass)
IP67G: LF1D/LF2D-EN
*4) The reinforced glass and polycarbonate illumination surfaces have the same appearance,
but have different degrees of protection.
