400w HMI Dimming compatible Multiple beam angles available 6,000m depth rated HIGH EFFICIENCY 400W HMI/MSR ARC LAMPS
DAYLIGHT COLOR TEMPERATURE 5600° K
COLOR RENDERING INDEX GREATER THAN 90
SUITABLE FOR COLOR OR B/W VIDEO IMAGING
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.

好象是舞台上用的灯

这个是钛的？

panx · 发表于 2011-4-6 08:54

不钛像呀！干什么用的？筒倒是筒，但不像是手筒！
