For those less electrically-inclined, the plug-in version of the Floodlight Cam Pro makes things even easier — provided you have an outlet nearby.

This fast adoption rate is being further accelerated by legislation on energy efficiency and by the reduction in the price of LED lighting solutions. Further reductions in cost will be realized as production increases and fewer light points are required to generate increased lumens/watt.

You need a Ring subscription As with all of Ring’s security cameras and video doorbells, you need to sign up for a subscription to use all of the Floodlight Cam Pro’s features. Most importantly, you can’t save any video. Granted, Ring’s fees — which start at $4/month — are among the most competitive among security camera storage subscriptions (you get to save 180 days of footage, for instance). However, other companies, such as Eufy, offer security cameras that don’t require subscriptions.

The Ring Floodlight Cam Pro ticks all the boxes as a great security camera, but competitors from Wyze, Nest, and others offer features such as local storage and higher resolution video that Ring’s camera lacks.

On the budget side of things, the Wyze Cam Floodlight v2 costs less than $100, yet has a higher resolution, brighter 2800-lumen lights, local storage, and a cheaper subscription plan.

We have developed a series of acrylic bead light diffusers that when compounded into a polycarbonate (PC) and PP bulb or tube produce a diffuse light with a high degree of light transmission.

Lack of filters While you can set up smart alerts for people or “other motion,” you can’t set up alerts specifically for animals or vehicles, as you can with cameras from Arlo, for instance. Nor is there a familiar faces feature (found on Nest cameras) which can notify you when the camera recognizes someone from a pre-set list of images. Given Ring’s long history in the market, it’s surprising it hasn’t released a feature like this yet.

Our top pick among floodlights is the Nest Cam Floodlight, which has a camera with the same resolution and 2,400-lumen floodlights. The Nest gets the nod, though, because you get person, package, and vehicle detection without a subscription, and has a three-hour local backup in case your power or internet connection goes down.

Bakelite plastic offers superior electrical insulation, making it a reliable material in demanding electrical applications. Let’s get into the details!

2020421 — It might be possible to use extreme ultraviolet (EUV) light to create electronic devices with smaller features like those we have today.

On its own, the Ring Floodlight Cam Wired Pro is a very good device, offering excellent video and audio, bright lights, and plenty of great features. However, among the best home security cameras, it doesn’t quite measure up to our top picks in the category, which offer even more features — like local storage — for the same or less.

RingFloodlight

For general lighting applications, blue LEDs that have a layer of yellow phosphor placed over the LED are used. The phosphor absorbs some of the blue light and emits yellow light. The unabsorbed blue light mixes with the yellow light to give white light.

Modeling studies and experimental testing has determined that diffusion and transmission in a PC/PP matrix are primarily controlled by three critical parameters: particle loading level, particle size, and refractive index of the particle.

Ring also does a good job of integrating its various products to work well together. For instance, if you have Ring motion detectors, you can program the Floodlight Cam Pro to start recording if they sense movement, and turn on Ring smart lights. Because Ring is owned by Amazon, it also works very well within the Alexa ecosystem.

UV in light in general is a highly effective means of killing surface microbes. UV sanitizers work by containing a lamp that emitlots of UV light.

More recently, aluminum has been replaced with plastics such as polyamide and polycarbonate containing heat-conducting fillers.

The Ring Floodlight Cam Wired Pro sits at the top of the company’s outdoor security camera offerings, boasting the company’s top-tier features, a 1080p camera, and two LEDs that pump out a combined 2,000 lumens, bright enough to show you everything going on in your yard at night.

Easy installation While it might seem intimidating to install a device into an electric box, Ring makes it very easy. After turning off the power, it was a simple matter of connecting three wires — all color-coded — and securing a few screws. In all, I was up and running in 30 minutes, which included the amount of time I had to climb up a ladder.

But before you go spending $249, you’ll want to check out the rest of this Ring Floodlight Cam Wired Pro review to see how it compares to the best outdoor security cameras, and if it’s the best option for your property.

The Ring Floodlight Cam Wired Pro first went on sale in May 2021. Its list price is $249, but you can regularly find it for less on Amazon and other online retailers. It’s available in white, black, bronze, and graphite. You can also purchase it as a plug-in model — you plug it into an outlet — or as a wired model, which replaces a traditional flood- or spotlight.

The greater the difference in refractive index the higher amount of scattering and light diffusion. Other factors such as particle size and loading level will also impact the amount of light scattering.  The performance of light-diffusing material is determined by measuring the total light transmission (TT%) and the amount of light diffused, utilizing a goniophotometer to determine the viewing angle (degree) at which light transmission is reduced by 50% relative to the maximum light transmission.

The materials utilized in a LED bulb are quite different than those used in a conventional incandescent and fluorescent bulb. LED bulbs not only consist of a LED but also a circuit board to control the electronics. The packaging utilized in LED bulbs and tubes is also different.

No local storage Unlike many of its competitors, Ring’s cameras have no local storage option, so if your camera loses its internet connection, there’s no way for it to record video. That could be problematic in the event your router loses power.

A standard LED light bulb utilizes 88% less energy than an incandescent bulb and 15% less energy than a CFL bulb and lasts for 20-30 years. This evolution in lighting, from flame-lit lamps to incandescent bulbs and fluorescent tubes and now LED, has been enabled by advances in material science and plastics. These advances include the development of new phosphors, microelectronics, and heat-dissipating plastics.

Uniquely designed with an ergonomic handle. Lightweight 6w lamp for easy handling. Durable plastic housing. Models available with shortwave, longwave UV.

New materials and lighting designs will enable LED lighting to deliver on the promise of increased energy efficiency and sustainability. Acrylic bead light diffusers will play a prominent role in providing light diffusion without severely impacting light transmission.

Two features in particular separate the Floodlight Cam Pro from the Floodlight Cam Plus: 3D Motion Detection and Bird’s Eye View. Bird’s Eye View gives you an overhead look at where someone walked in front of the camera, though it’s limited to a 30-foot range. They’re both nice-to-have features, but I’ve found it hasn’t added a lot to my overall experience using the camera.

Although LED lighting has been adopted in applications including displays, signals, automotive, and mobile devices, the largest growth market is in residential and commercial lighting. This market includes the replacement of standard bulbs and tubes with LED bulbs and LED tubes, troffers, light boxes, and light panels for illumination. The growth rate for LED lighting will be substantial and will continue to replace conventional lighting. Therefore, light diffusion compound demand will grow in the near future.

Among Ring’s own floodlight cameras, most homeowners will find the $199 Floodlight Cam Plus more than sufficient for their needs; unless you have some obscured area of your yard, the Floodlight Cam Pro’s 3D Motion detection and Bird’s Eye View didn’t really add all that much to my experience using the camera. If you’re invested in Ring’s ecosystem, its floodlight is a great addition if you want to keep tabs on your entire property. But if you’re just building out your smart home, it’s worth shopping around.

Two features are especially noteworthy. First is the aluminum finned bulb body which is part of the LED heat-dissipating system. This is required to dissipate the heat and improve the life and long-term performance of the LED.

For about $100 less, Ring also offers the Floodlight Cam Wired Plus, which has the same resolution camera, but lacks HDR, 3D motion detection with Birds-Eye zones, 5.0Ghz Wi-Fi, and an array microphone that helps you hear sounds better.

Video resolution: 1080p HDR Field of view: 140° horizontal, 80° vertical Night vision: Yes, color Audio: Full duplex Lights: 2000 lumen Siren: 110 dB Local Storage: No Battery Powered: No Weather Resistant: Yes Wi-Fi: 802.11 b/g/n (2.4GHz and 5.0GHz) Smart Home Compatibility: Alexa, Google Assistant, IFTTT Cloud Storage: $4/month ($40/year)

The second feature involves the elimination of the need for a sealed glass bulb cover. Since the LED is itself encapsulated there is no need for an inert or for sealed metal vapor atmosphere. This allows light designers much more flexibility in developing new lighting fixtures. Additionally, the bulb cover can be made of a plastic such as a polycarbonate or polymethylmethacrylate making for a more rugged bulb.

A Light Emitting Diode is an electronic device that produces light when an electrical current is passed through it. The wavelength/color of the light that is emitted is dependent on the semiconductor and phosphor that is used.

Great image quality While the Floodlight Cam Pro doesn’t have the highest resolution among outdoor security cameras — Eufy has a 2K camera, and Arlo has both 2K and 4K cameras — Ring’s 1080p resolution was plenty crisp and clear both day and night. It was easy to make out details in people and objects, though it was harder to discern those who were about 30 or more feet from the camera.

Europlas Light Diffusion Compound, which gives the optimal balance of high light transmission and adequate light diffusion in polycarbonate to produce a LED bulb of high lumens per watt and reduced glare.

A good feature set Apart from its eye-searing LEDs, the Floodlight Cam Pro has a 110-decibel siren that will definitely get your neighbor’s attention if you set it off. In addition to movement, it can also listen for glass breaking, car alarms, and dogs barking, and start recording if it hears any of those sounds.
