Night Lighting Units

The lighting units I designed and built, are intended to produce an adjustable intensity cone beam very high brightness pure 6200K white light source.

Nothing like it exists available for purchase, and they can reach nearly 500m at full power. Their dispersed output does not produce a noticeable beam, unless you stand still, and their colour temperature is perfect for true colour rendition. You can spotlight very subtly.

At their lowest output they barely glow, at their highest about 200,000 Candela about the same as a million candlepower torch.

Flash at night rapidly disperses with distance and also can create bounce reflectiions that ruin a dark night shot.

The light cone is only 20 degrees angle and allows you to highlight points of perspective without washing out surrounding areas, the narrow cone reaches a great distance. Below at full power on a full moonlit night, behind a wall looking skyward.
Below, taken recently, and probably a bit overbright, was influenced by the atmosphere in the pitch dark chasm in the moonless night, as huge swells tried to batter their way past this rock (and me!).

Below used at a low power setting just to highlight a tree, though it looks like a bright spotlight, the beam was very weak.

All in all a very handy tool for illuminating subjects at distance with a cool white, adjustable brightness, non dispersing beam
