(Light bulb color LED that is easy to handle in astronomical observations) Generally used incandescent bulbs have a wide wavelength range and include a lot of light near 55 nm wavelengths with the largest effect on dark eyes. The SG-L02 uses a light bulb color LED that avoids the wavelength range of around 55 nm, ensuring moderate visibility while reducing the effects of eye darkness. Comfortable support for people who love astronomical observation
Classic Red LED for astronomical observations: Equipped with a red LED that is minimally affected by the darkness of the eyes, ensuring minimum visibility. A classic astronomical observation
Variable LED Brightness, Starting Dark and Initial Illumination Color: The brightness of the bulb color LED and red LED are steplessly adjustable (bulb color is approximately 3 - 42 lumens and red is approximately 0.28 - 7.62 lumens). In addition, it is always the darkest of the initial light to minimize the effect of eye darkness. You can freely choose the initial light color from the bulb color or red color
USB Rechargeable: Built-in rechargeable lithium-ion polymer battery. Use the included charging cable to charge it via a USB charger or USB power bank. Economical for recharging and reuse
