4.7 Effective Intensity Correction
Depending on the flash code selected, the effective intensity may be adjusted.
As per IALA Recommendation E-200 Part 4, effective intensity is defined as:
“The luminous intensity
of a fixed (continuous) light, of the same relative spectral distribution as a flashing light, which would
have the same luminous range as a flashing light under identical conditions of observation”.
Sealite has provided you with the most common methods for effective intensity adjustment as follows:
• Schmidt-Clausen
• Allard
• Blondel-Rey-Douglas
• Allard-Ohno-Couzin
PLEASE NOTE:
the lantern Effective Intensity Correction is set to “None” as default. No effective
intensity correction will therefore be applied to the lantern setting.
To program the lantern Effective Intensity Correction (see Image 5):
• Click the “Intensity” tab at the top of the Sealite Lantern Programmer
• From the “Effective Intensity Correction” box, select the desired lantern effective intensity
correction mode from the list available
• Click the “Set Intensity” button to send the new setup instruction to the lantern
