Salvo Diving Equipment (Salvo) has come out with a new line of LED-based diving lights. LED lights sip power and are incredibly durable. but that usually came at the cost of being difficult to focus. Salvo has sourced a LED-emitter that they feel have fixed this limitation.
This line of LED-based lights have a 6 degree focused beam which is rated @ 50,000 hours. The light also has 5 output levels the diver can choose from, 20%, 40%, 60%, 80% and 100%. These means that battery bur- time can range from 4 to 20 hours depending on output setting.
They were so impressed with these LED emitters that that discontinued all of there 10 watt HID lights! They are also working on some versions for video lights but as of now, if you want bright video lighting, you are better off sticking with HID or HMI as LEDs haven’t developed into this space yet.
