Color Filter LF-N Set

Condenser Lens LF-N

■ LF800-N Features ■

●Super narrow 5 degree coverage, dual use underwater/land
Optional accessory for changing color/even narrower beam

The LF800-N effectively converts original 125 degree (approx.) spread beam from LED module to super narrow 5 degree (approx.) thanks to its unique optical system. (*1)

In addition to general use on land or dive light underwater, this product is best suited as a pointer or powerful constant lighting source for photography/videography thanks to its native 5000K(approx.) beam.

Optionally available "Color Filter LF-N Set" (*2) consists of "Red Filter LF-N" which changes color not to stimulate marine lives and "Blue Filter LF-N" which calibrates native light to deliver ideal color tone for underwater imaging. Other optional "Condenser Lens LF-N" (*2) functions to condense native narrow light further to expand application of this product as like "ultra- macro shooting with constant light".

Unique optical construction delivers light within fixed range and will have center sport out of the working range as per below table.
"Color Filter LF-N Set" and "Condenser Lens LF-N" are designed for underwater use only and not usable on land.

Theoretical working distance to illuminate a subject without significant center spot and not same as the maximum distance this product can deliver light.
When illuminating a subject at approx.55cm/21.6in away or greater, using Condenser Lens LF-N will have bigger lit area.

●Powerful 800 lumen (*5), two power setting
Only with 3 x AA batteries supporting handy yet great cost performance
