Vixen Astro LED Lamp SG-L02
For the perfect LED lamp you must-have for the night observing sessions! We introduce this high-quality and functional Astro LED Lamp SG-L02 by Vixen. For astronomical observation, It is vital to adapt your eyes to the dark environment.
The shady sites are bad for visibility, and you need to prepare a lamp for setting up your equipment for Astro-imaging or observing. However, general lamps emphasize illumination intensity as important than protecting your eyes against the bright light. If such a lamp is used for night watch, it will be difficult for your eyes to see stars due to the solid stimulation.
Our first Astro LED lamp is a solution to this problem in which the SG-L01 red color lamp was incorporated, yet the range of that red light is narrow and not necessarily good at visibility. We have adopted the LED lamp's light bulb color to improve visibility with our Astro LED lamp SG-L02, and this allows for avoiding unwanted influence on the eye's dark adaptation. The LED lamp's brightness is adjustable between 0.28 and 7.62 lumens in red color illumination and between 3 and 42 lumens in light bulb color.
Generally, white light bulbs have a wide range of wavelengths of light, and among them, the light near 555nm is mainly included. This range of light significantly influences the adaptation to dark environments the human. On the other hand, the LED lights feature narrow peak wavelengths and designing a light source so that the light near 555nm is not included is possible. The Astro LED lamp SG-L02 uses LED light bulbs made not to emit the 555nm light & its adjacent. It allows us to keep moderate visibility while depressing the influence on your eye's adaptability.
The brightness of illuminationare steplessly adjustable ( 3 up to 42 lumens) in a light bulb color and that (0.28 up to 7.62 lumens) in red color. The lighting always starts with the dimmest position, and it's possible to gradually increase the intensity to protect night vision. You can choose either the light bulb or the red color to start.
The rechargeable lithium-ion polymer battery is used. Using the supplied USB cable, you can refresh the battery from a USB battery charger or USB mobile battery. It is economical to use the battery repeatedly by recharging. Condensation and dew that may happen during the observing sessions at night work fine with no fear of influence. Usable in the rain (IPX4 class waterproofness).
It has two different lengths of straps—the long and the short ones. The long strap is available as a head strap, and the short is a wrist strap. By joining the two straps together, it will be usable as a neck strap. The detachable pocket clip is helpful for a shirt, collar, hat, or books, and it is available for a place if the strap is hard-to-use. Buy to see it yourself! Add to cart now!
