The SeaArc2® HMI/MSR underwater lights are 3-4 times more efficient (lumens/watt) than comparable tungsten-halogen lights. Since there is no filament to break, SeaArc2® lights are less sensitive to vibration and shock. The SeaArc2® HMI/MSR lights are built using the 400W MSR/400HR lamps.
HMI/MSR lamps are AC-operated discharge lamps in which the luminous arc burns in a dense vapor atmosphere comprising mercury and the halides of rare earths. The MSR in the part number indicates Medium Source Rare earth (MSR) elements, the number indicates the wattage, and the HR designates Hot Restrike.
HMI lamps have a color temperature of 5600°K. Advantages of HMI/MSR lamps over HID lamps is they warm up in 1-2 minutes and have an instant restrike ability. HMI lamps can also be dimmed when operated from a ballast with dimming circuitry.
A properly designed ballast is required to operate a SeaArc2®. SeaArc2® HMI/MSR ballasts can be powered from either AC or DC voltage. It accepts a nominal input voltage of 120V or 240V, ranging from 110V to 300V. The ballast provides properly conditioned AC voltage/current required by the ignitor circuit and lamp in the lighthead.
The HMI ballast can even power DeepSeas proprietary TI/EB (Thallium Iodide/ElectronicBallast) lamp, a specially configured Thallium Iodide (TI) lamp. TI lamps produce an intense, monochromatic green light output (535 nm) which is close to the transmission "window" of seawater. The TI lamp offers maximum light penetration for long range monochromatic imaging applications such as submersible navigation and subsea surveying. TI lamps typically operate from HID magnetic ballasts. However, using a special ignitor, this lamp gives users the flexibility to use one type of ballast to power an HMI or a TI lamp. You can freely swap lightheads with no modification to the ballast. DeepSea offers a dual ballast housing, so that users can operate a TI/EB and HMI from the same housing.
There are options available in the types of reflectors, depth rating, types of material, and types of ballasts. Please call DPS&L for assistance in determining the best combination of options to meet your requirements.

大~優~{:1_231:} 32000 流明 这是深海照明吧！！！ 看起来很给力{:1_268:} 好东西。 船用摩斯信号灯。。。大概是军用品，但不算亮。 这是镀钛还是？？？ 本帖最后由 人生三愿 于 2011-7-16 23:54 编辑
