Hardwired lights give you nonstop power around the clock. Battery-operated lights can be placed almost anywhere. And solar lights offer added convenience.

Group Ring Lighting together to customize how they illuminate. If one light detects motion, it can brighten up a pathway or make your whole yard shine.

You can group Ring Lights together and connect them to your other compatible Ring devices and select Alexa-enabled devices with the Ring Bridge.

Your Ring Bridge should be placed indoors within reach of a good Wi-Fi signal and in a centrally-located place relative to your Ring Lights. Best practice is not to install it in a metal cabinet or closet, but to leave it out in the open so the signal is not restricted.

The throughput of Rubin Observatory, or the percentage of an object's light the optical system can capture, is 63% at the center of the detector (or image plane) out to a field radius of 0.7 degrees, gradually dropping to 57% at full field (or 1.75 degrees). The resulting etendue (the product of aperture area in square meters and field of view in square degrees)  is 319.5 m2deg2.

Ring Bridge is the hub of your Lighting. It enables smart security features and connects your Ring lights with other compatible devices.

Pathlight and Steplight- The Solar Pathlight or Solar Steplight can also be recharged by bringing the unit inside and connecting it via micro USB. The unit will blink on and off as it charges, and then glow on when it is fully charged.

The wavelengths of light for which the optical system is optimized range from ultraviolet to near-infrared; these wavelengths are divided into spectral bands labeled u, g, r, i, z, & y to identify wavelengths of specific interest. For example, an infrared, or r, filter might be used when observing areas obscured by dust. Infrared wavelengths can pass through dust, so the filter will enable imaging of sources behind the obstruction.

Financial support for Rubin Observatory comes from the National Science Foundation (NSF) through Cooperative Agreement No. 1258333, the Department of Energy (DOE) Office of Science under Contract No. DE-AC02-76SF00515, and private funding raised by the LSST Corporation. The NSF-funded Rubin Observatory Project Office for construction was established as an operating center under management of the Association of Universities for Research in Astronomy (AURA).  The DOE-funded effort to build the Rubin Observatory LSST Camera (LSSTCam) is managed by the SLAC National Accelerator Laboratory (SLAC). The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 to promote the progress of science. NSF supports basic research and people to create knowledge that transforms the future. NSF and DOE will continue to support Rubin Observatory in its Operations phase. They will also provide support for scientific research with LSST data.    Contact   |   We are Hiring

The system length is a very compact 6.4 m from the vertex of the secondary mirror to the vertex of the tertiary mirror. The Rubin Observatory primary mirror is highly annular (ring-shaped), having an outer clear aperture of 8.36 m and an inner diameter of 5.12 m, giving an effective collecting area of a 6.67 m filled aperture. The 1.8 m diameter hole in the secondary mirror holds the camera body and associated readout electronics. The hole in the tertiary mirror is used to mount equipment for maintaining precise control of Rubin Observatory's optical alignment.

The Ring Bridge brings it all together in Ring app. There, you can completely customize your smart controls and create action combinations. For example, if you connect a Ring Lighting Floodlight to a compatible Ring Video Doorbell via the Ring Bridge, it can activate your doorbell as soon as your floodlight detects motion.

These lights are really nice. The color of the light itself is very pleasing. They are easy to install and group together to light an entire walkway when motion is detected by just one of the lights.

Enjoy the flexibility of energy-efficient smart LED bulbs. Simply screw into compatible lamp sockets for smart control from anywhere.

Light every step you take. Pathlights are perfect for driveways, walkways and gardens while Steplights illuminate decks and stairs. Already have landscape lights? Connect compatible lights to our Transformer to control them from the Ring App.

After bouncing off the three mirrors, light will reach the Rubin Observatory LSST Camera. The camera optics consist of three large fused-silica lenses and a filter. The largest lens (L1) is 1.55 m in diameter, half again as large as the 40-inch Yerkes refractor—the world's biggest astronomical refracting telescope. The 0.69 m third lens (L3) also serves as the vacuum barrier for the focal plane array (FPA) cryostat and requires a center thickness of 60 mm. LSST Cam's filters are very large, with a clear aperture of 0.75 m. All of these attributes give LSST Cam superb optical performance.

Have your Lighting automatically illuminate your yard or walkways at the same time every evening and turn off when you want them to.

The Ring Bridge also allows you to connect your lights to select Alexa-enabled devices, so you can hear announcements, turn on Ring Lights when motion is detected, and adjust the settings at the sound of your voice.

Shine a light from up high with mounted lights. Illuminate large areas like the driveway and backyard with Floodlights for security and safety. Or focus on a single area like a porch or shed with Spotlights.

In the picture to the left, light from a source in the sky reflects off the three mirror surfaces, through the refractive lenses and is captured by the detector in the camera. The fast optical system coupled with the large collecting area of the mirror and sensitive detectors makes it possible to take very deep images with a very large field of view compared to other 8m class telescopes. Over 10 years, more than 800 images will be taken of each point on the sky.

I purchased four of these along with the Bridge and these things are sturdy – they work. The brightness levels are very good and they interact with your other motion sensors.

Rubin Observatory views a 9.62 square-degree patch of sky, more than 40 times the area of the full moon. This huge viewing area is the result of the telescope's unique optical design: a compact three-mirror telescope augmented by a large refractive corrector, the whole capable of delivering a 3.5 degree field of view covering a 64 cm diameter flat focal plane. The starting point for this design was the Dark Matter Telescope proposed by Roger Angel, director of the Steward Observatory Mirror Lab at the University of Arizona, and his collaborators in 2000.

Floodlight- The Floodlight Solar' battery is a Ring Quick Release Battery that can also be recharged using a Quick Release Battery Pack.

The image quality is better than 0.3 arcseconds (1/3600 of a degree) for all bands as measured by the 80% encircled energy of the image of a point source, which is a standard measure in optics of how well the optical system focuses the gathered light. For the longer wavelengths corresponding to the r, i, z & y spectral bands, the 80% encircled energy is ~0.2 arcseconds or better. Typically imaging will then be limited by the atmosphere, which averages around 0.7 arcseconds.

Always come home to a brightly lit house. Add Lighting around your home and control them from the Ring App. Turn lights on or off while you’re away. Link your lights to select Ring Video Doorbells and Security Cameras, so they shine when motion is detected. And best of all, choose from new solar-powered options for added flexibility.

Nice addition to my Ring of Security. I live on a dark trail so at night it really lights up the walkway and street. The product feels durable and well built. Definitely will be purchasing more in the future.

Without the Ring Bridge, Ring Lights will shine as soon as motion is detected or the light is turned on, but you won’t be able to customize your settings. You also will not be able to pair your Ring Lights into groups, receive notifications, or connect Ring Lights to other compatible Ring or Alexa-enabled devices.

The Rubin Observatory Simonyi Survey Telescope consists of three aspheric (nonspherical) mirrors: an 8.4-m primary mirror, a 3.5-m convex secondary mirror, and a 5.0-m tertiary mirror. The primary and tertiary mirrors were fabricated from a single piece of Ohara E6 low-expansion glass, resulting in the monolithic Rubin Observatory Primary/Tertiary Mirror (M1M3). The Rubin Observatory Secondary Mirror (M2) is the largest convex mirror ever made. Details of these mirrors can be found in the mirror design section.
