A Little Ray of Sunshine In Your Hand: Understanding Different Types of Dive Lights

Why Use Dive Lights?

If all you're used to seeing of coral reefs is blues, greens, and dull reds...你错过了!

水下十到二十米,水过滤到深蓝色的所有光线。这里的珊瑚和你在表面附近看到的那样多彩。它只是缺乏颜色的光。

另一方面,如果你从未见过黑暗缝隙或悬垂的壁架内部,你不知道你缺少了什么。龙虾的大小圣伯纳德在这里闲逛。

解决方案?让自己潜水。新金沙线上它不一定是巨大的,特别是如果你对夜晚,残骸或洞穴潜水不感兴趣。对于开放的水潜水员来说,你想要新金沙线上一些小的东西剪辑到你的公元前委员会,在那里你不必担心它,直到需要它。

For night dives, size matters.

如果你一直将在手中握住它,请用更大的灯光,使您看到更多,获得更好的颜色,电池持续更长时间。

无论您将要用的内容,有三件事要留意灯光:轻型,潜在的照明技术和所用电池的类型。


新金沙线上潜水灯类型

基本上有三种类型的潜水灯:主要,次要和视频。新金沙线上

Primary lights

Primary dive lights are the big lights used by night divers and open water divers in murky water. Canister lights, even bigger ones, are the cave and wreck divers' favorite lights. Like video lights,canister lights have a wide beam.

他们是为了最后一个完整的潜水,必须的新金沙线上be powerful enough that you can maneuver without any other source of light. Of course, you always need to carry a backup light in case the primary fails. Primary lights can be tungsten, HID, or LED. Nowadays, they're mostly LED.


Secondary lights

小型手持设备售出白天潜水使用或备用(二级)灯。这些灯非常适合在30米的墙壁上检查珊瑚的真实颜色,或在壁架下窥视到20公斤石斑鱼。新金沙线上

You can even use them to get your dive buddy's attention if he or she is a little too far away. Small handheld lights are either tungsten or LED, and generally powered by disposable batteries.

Video lights

Video lights are the other type you'll see on open water dives and are quite powerful. The good ones won't have center-heavy hot spots in the beam, but a wide, even flood. All will have mounting points for attaching to a video rig. In terms of technology, video lights are generally HID or LED, and their light color is critical. Video cameras are extremely sensitive to color differences.

You want a video light that gives out pure white light in order to get eye popping colors on screen.


新金沙线上潜水轻型技术

当我说“钨”,“HID”或“LED”时,我指的是潜在的技术,他们如何制作光线。市场上有三种潜水轻型技术。新金沙线上即使你只使用一个,也是了解不同类型的工作原理是一个好主意。

钨/卤素/氙气

卤素和氙气灯泡像普通手电筒一样工作。这些灯在高压气体的灯泡内具有精细的钨丝。他们已经遍历了最长,并提供出色的色彩再现。

不幸的是,他们不是很聪明。

The beam is quite yellow and doesn't penetrate far under water. The batteries also don't last very long. On the upside, they're the cheapest,有时到目前为止。

高强度放电(HID)

这些灯越来越难以找到。它们还使用灯泡,但在特殊的气体环境中有一个小弧而不是灯丝。HID灯会产生当天在表面上方看到的光的颜色,这使得它们成为视频录制的理想灯。Color rendition with HID is as good as you can get.

HID光的光束进一步在水下而不是卤素灯泡。它们是每瓦的三到五倍亮,消耗较少的力量。然而,它们比LED更昂贵,效率低。

Light Emitting Diode (LED)

LED是最新的,最热门,可能是市场上最受欢迎的技术。您知道从计算机上的LED,因为闪烁的红色,蓝色或指示电源的绿灯。您可能拥有至少一个LED手电筒,即使您没有意识到。

LED提供的优惠是任何潜水轻型技术的最佳效率。新金沙线上这意味着您变得更加明亮,更持久的电池。即使是小型LED的潜水光线也会在水下非常明亮和新金沙线上持久。另一方面,最大的罐头LED灯是致盲的。

Because LEDs contain a tiny chip, they're extremely rugged. Their primary disadvantage is color, which isn't as good as HID's. LEDs tend to be a little on the blue side, so if you're shooting a video, do a comparison before your purchase.


可充电的VS.一次性电池

最后,关于可充电与一次性电池的一句话。

For the longest time, occasional divers were always told to use disposable batteries. This is still mostly true. If you dive only once or twice a year, disposable batteries are the most reliable way to know that your light is going to last the whole dive. However, if you dive a little more frequently, they can get expensive. Also they aren't particularly great for the environment. Rechargeables now look a little more attractive.

Just keep one thing in mind with rechargeables. Keep them charged in order for them to last on the shelf. Modern technology, fortunately, has gotten a bit better than the NiCds of old. So-called "ready to use" nickel metal hydride batteries like the Sanyo Eneloop series can last for a year or two on the shelf without losing a charge.

锂电池不太好but they're getting better. Though they should be kept plugged in to a maintenance charger when not in use, lithium batteries offer more power per volume than any other technology. This makes them a particular favorite of underwater videographers and tech divers,对于锂包,可以为长潜水的灯光电源非常明亮。新金沙线上

The newest, integrated lithium battery lights are worth mentioning as well.

现在有一些带有内部锂电池的手持式灯光。这些长时间提供大量光,因为只有工厂可以为电池充电,you don't have to worry about flooding. On the other hand, you do have to send them in and pay a fee to swap out the batteries every few hundred dives.
