Typical LOR (lumen output ratio) of a reasonable MH downlight would be around 0.6 meaning that you get 60% of the lumen output of the lamp out of the fitting. Any manufacturer should be able to provide the LOR for a particular fitting
Planets viewed through a telescope typically appear as small, round discs with some surface features visible. They may also show distinct colors, such as the reddish hue of Mars or the white clouds of Jupiter. The larger planets, like Jupiter and Saturn, can also reveal their moons as tiny specks of light nearby.

Selenate can be converted to selenium through a reduction process. This reduction can be achieved through biological means, using bacteria or other microorganisms that are capable of reducing selenate to elemental selenium. Alternatively, a chemical reducing agent such as sodium sulfite or sodium borohydride can be used to convert selenate to selenium.
Pseudoephedrine was first discovered by Nagai Nagayoshi in 1889 through a reduction reaction of ephedrine.
In a fuel cell, reduction takes place at the cathode. This is where oxidants, such as oxygen, gain electrons that have traveled through the external circuit from the anode, where oxidation occurs. The reduction process at the cathode is essential for generating electrical energy in the fuel cell.

Glass is not a good reflector of light as it allows most of the light to pass through it. A small amount of light may be reflected off the surface of glass, but it is generally transparent and allows light to transmit through it.
Yes. For example, I can see the moons of Jupiter through my 6" reflector which I cannot see unaided.
Glass is not a good reflector of light compared to materials like mirrors or metals. While it can reflect some light at its surface, most of the light passes through it, making it a better transmitter than a reflector. The reflection that does occur is typically around 4% for each surface of glass, which is relatively low. Therefore, while glass can reflect light, it is not considered an effective reflector.
Insulated recessed lights in a home provide energy efficiency by reducing heat loss through the ceiling, improving the overall insulation of the home, and enhancing the lighting quality in the space.

Gold is a better reflector than glass because gold has a higher reflectivity across a wider range of wavelengths, especially in the visible and infrared spectrum. Glass does not reflect as much light and instead allows light to pass through, making it more transparent than reflective.
Reflector telescopes are cheaper to make than refractors of the same size than passing through it, only one side of the reflector telescope's Often a secondary mirror is used to redirect the light into a more convenient viewing spot.
Water is a poor reflector of light. It allows light to pass through easily, resulting in limited reflection. This is why bodies of water appear transparent or clear, rather than reflective like a mirror.
Yes, Earth is a good reflector of heat through a process known as albedo, which is the reflection of sunlight and heat off its surface. The Earth's surface reflects about 30% of incoming solar radiation back into space, helping to regulate the planet's temperature.
