![]() On the other hand, lumens is important for knowing how much light a single light source emits. Lux is a measure of how much light falls on a particular surface, and can be the result of multiple light bulbs and even daylight mixed in. Indirect daylight: 10,000 lux, or 200 micromoles per second per sq meterĭirect daylight: 100,000 lux, or 2,000 micromoles per second per sq meter Common lux levels are listed below:ĭark, cloudy day: 1,000 lux, or 20 micromoles per second per sq meter Without a sufficient lux level, it can be difficult to read or take good photographs. This is the crucial metric if you want to know how bright a surface will appear, such as a tabletop, reading material or photography subjects. Lux is important for knowing how bright a particular surface appears. ![]() As you move farther away from the center, lux will decrease. For example, you may see "1000 lux at 4 feet" - if you only see a lux rating, you will not know what distance this is measured at, and you will not be able to make a valid comparison.įor most directional light sources such as LED spotlights, the center of the beam typically has the highest lux reading. Therefore, when you look at a lux rating for a light bulb, you must always make sure there is a distance associated. This is due to the dispersion of light as one moves away from the light source. Note: We recommend that you don’t look directly into this light to avoid any damage to your eyes!The closer to the light source, the higher the lux reading. The case warms up to a comfortable 55☌ (131☏) when operated in air and stays much cooler in water. The light operates on 10-48V inputs and can accept PWM signals from 3-48V! It is compatible with many common boards like the Arduino, Raspberry Pi, and PixHawk. Just connect the yellow signal wire to the power wire and it will turn on! A switch can be used here to make this even more convenient. The case has a built-in mounting bracket with two M3 threaded holes for mounting to your vehicle.įor those who want to use the light in other applications, like scuba diving, the light can be operated without a PWM signal. The specially designed injection molded acrylic lens ensures a consistent beam angle in both air and water. That means you only need one cable coming from the main watertight enclosure to control multiple lights! By default, the second cable penetrator is blank, but the light comes with a second penetrator to allow a second light to be connected to the first (daisy-chaining). It’s housed in a rugged hard-anodized aluminum enclosure with two cable penetrators at the rear, allowing it to go to a depth of 500m. An exponential brightness curve makes it intuitive to use effectively. In addition to really high brightness, the Lumen is designed for very low brightness output, which is important to be able to illuminate the scene without washing out the colors or brightness. The color temperature is 5700K, similar to most dive lights and ROV lights. Using a high-efficiency Cree XLamp LED, the light outputs over 1500 lumens at 15 Watts – brighter than most car headlights! It has a 135 degree beam angle for wide illumination in front of an ROV. Exponential brightness control with much lower minimum brightness output.Built-in mounting holes on the side of the case (M3 thread).Automatic, smart over-temperature compensation for maximum light output and safety in air.Daisy-chainable to connect multiple lights from a single connection.Simple on/off control with no signal needed.Fully dimmable control using a PWM servo signal (1100-1900 μs).We designed this underwater light specifically for this purpose and it has a few neat features: The Lumen Subsea Light is a blindingly bright LED light for use on ROVs, AUVs, and other subsea lighting applications.
