the Stand Alone (SAP) light head and VPP-67 solar body. Note that the solar power regulator is
located in the lantern and not in the VPP-67 Solar Power Pack. In applications requiring more solar
power the solar power pack can be substituted with the larger capacity VPP-66.
The VLB-67 is designed with many features to allow the user to customise the beacon for any
application. Programming is done using the Vega Remote-02 Infrared Programmer or by a
computer using the PROG-01 Programming kit. Both the Remote-02 and Prog-01 items need to
be ordered separately.

Approvals
The VLB-67 LED beacon has been approved under US Coast Guard regulations CFR33 part 67
for use as a Class B or C light for artificial islands and structures in the Gulf of Mexico (USCG
District 8).

Range and Power
2.1
Effective Intensity Settings
The VLB-67 beacon supports a number of effective Candela settings.
Appendix B of the manual provides the following information:
x
The Effective Intensity settings available for each colour
x
The current the beacon will use at each intensity
x
The Peak Candela and Peak Current of each colour
While the VLB-67 is normally only used at night it is possible to operate the beacon during the day
using a different intensity setting than is used at night.
2.2
Automatic Schmidt Clausen Correction
Effective intensity is the intensity required to see a continuously
“
on
”
light (fixed character) at a
certain distance. For example 39 Candela is required to see a fixed
“
on
”
light at 4NM when the
atmospheric visibility is 10 miles (0.74T).
When a light is flashed the intensity must be increased to maintain the lights visibility at the
required distance.
This increase of intensity is the “Peak” intensity for the flash character.
The
VLB-67 automatically handles this process according to the Schmidt Clausen multiplier for LED
lights: (Flash period in 0.2)/Flash period in seconds
The VLB-67 beacon will not operate above its maximum candela capability. When programming a
flash character the user should check that the peak candela required for a flash character at the
required range is below the maximum intensity. The VLB-67 will cap the intensity at the maximum
candela allowed, reducing the range of the light.
