Setup: You can set up most smart bulbs in just a few minutes.

Some bulbs use only a Bluetooth connection to the smartphone, which limits how far away you can be to control the light it may also prevent some types of automation.
A mesh network like that can be more robust, especially in large homes or where the Wi-Fi signal is weak. Some rely solely on Wi-Fi connections directly from the bulb to the phone, while others connect on a separate wireless network, such as Zigbee, through a gateway or hub that your phone connects to over Wi-Fi. Wireless network: You can control most smart bulbs wirelessly through smartphone apps.We looked at those features, as well as actual primary and secondary colors and each bulb’s color rendering index (CRI) rating-a measurement of how accurately each bulb can produce colors. Color: While we considered color-adjustable, tunable-white, and plain-white smart bulbs, we found color-adjustable bulbs to be the most feature-rich.We use a light meter to measure each bulb’s lux, using the same equipment, under the same conditions, at various angles and dimming levels. Lux is another standard measurement, which is superior because it describes how effectively the light spreads. Lumens are a measurement of the total potential light a bulb emits. Brightness: We primarily tested 800 to 1,100 lumen (A19-style) bulbs that are roughly equivalent to a 60-watt or 75-watt incandescent lamp bulb.However, there are trade-offs, which we discuss below. Some systems-such as Apple HomeKit, Amazon Alexa, and Google Home-let you control the lights with your voice and use lights from multiple brands, so you’re not stuck with one ecosystem. Smart-home compatibility: Smart lights that are integrated with other devices become even more useful, so you’re likely to use them more frequently.App features: Some lighting apps offer only basic on/off and scheduling options others include special effects, as well as features such as an Away Mode that randomly turns lights on and off to mimic occupancy.
So for your 100W flood light with CFL bulbs, it’s ok to use our 40W LED flood light to replace it. so we can use a 20 watts LED light to replace the 50-watt Compact fluorescent lamp give 3000 lumens. √ For compact fluorescent lamps, its luminous efficiency is about 60 to 70lm/w. so we can use 25 to 30 watt LED light to replace 50-watt Compact fluorescent lamp gives 4000 lumens. √ For high-pressure sodium lamps, their luminous efficiency is about 80 to 90lm/w. So can we can use a 15 watts LED light to replace the 50-watt metal halide lamp give 2500 lumens. √ For metal halide lamps, their luminous efficacy is 50lm/w. Because different types of lamps have different luminous effects, when replacing traditional lighting with LEDs, the lumens of the old and new lamps should match, not the wattage.īelow are the examples to replace different kinds of light fixtures. Wattage refers to the energy consumed by LED lamps, and lumens represent brightness. They mistakenly associate the wattage with the brightness, but the wattage does not represent the brightness of the lamp.
When people choose LED lamps to replace existing lamps, they believe that the wattage of the new and old lamps should be the same. For example, when doing lighting design for the football pitch, a stadium, or a port, we can use both LED flood light and LED spot light (We call LED stadium light). In our opinion when an area should be lighted, the LED light with narrow beam angle(spotlight) or wide beam angle(floodlight) can be used together so this area can be lighted with good uniformity. When larger areas, such as driveways, stages, warehouses, parking lots, tunnels or any other areas should be illuminated, you can use LED floodlight with a wide beam angle which is with wide and even light coverage. When specific points such as display objects, wall art, architectural details, or landscape features should be lighted, you can choose outdoor led flood lights with a small beam angle.Ģ. When its output power and lumens are the same as the spotlight, it can illuminate a larger space.Īpplication of LED spot light and LED flood lights:ġ. √ While LED flood light can spread a light whose beam angle can reach 120 degrees. This kind of beam angle is more concentrated and easier to control and point. √ LED spot light projects a narrow beam of light, normally no more than 45 degrees.
