LED vs HID TechnologyHeraclitus, a Greek philosopher (about 500 BC), wrote "Nothing endures but change."LED technology has advanced to the point where LED lights are now much brighter than 10W HID and at least equal to 15W HID. Although LED is lower cost with a better color temperature, HID does still offer some higher light output solutions. The 21W HIDs are a few hundred lumens brighter and LEDs aren't going to catch up to the light outputs of 35W or 50W HID anytime soon. The high wattage HIDs are also used to light professional video. The HID bulb and reflector can create super tight 4-degree focus beams and also provides beam width adjustability. However, LED is catching up and the latest generation of LEDs are now offering 6-degree beams. The cost and hassle of bulb replacement for HID compared to the long life, robust nature and extremely low failure rate of the LED means that HID is nearing end-of-life for low-to-mid range dive light applications. There are certainly still HID lights in the market and plenty of long time divers will swear by the HID lights they own. But when considering the purchase of a new light, the reality is that for most exploration diving the incredibly bright and lower cost LED lights are a terrific value. When shopping for lights, it can be very difficult to compare published specifications. To help make it a bit easier, we've got some beam comparisons of the lights we sell. |
