![]() ![]() Sylvania High Definition BR30 Floodlight LED (not widely available yet, review coming soon).I think that about covers it, but if you want to know more about the bulbs I tested for this roundup, here they all are: Chris Monroe/CNET Anything else I should know? This new floodlight LED from Sylvania isn't available outside of California yet, but it's efficient, putting out 93.7 lumens per watt. I'm just here to help you find those "just right" bulbs a bit faster - or more efficiently, you might say. You've got a lot of good options these days, so there's really no need to compromise. Like I said, LEDs like these are designed to be durable and waterproof and last years, so it's well worth buying ones that you'll actually like living with. They're also just really damned good at taking pictures of light bulbs.Īll of that said, the most important thing isn't what I think when I'm taking readings in our lighting lab - it's what you and your family think after screwing the bulbs in and turning them on in your living room or other area. Our photo and video team (Tyler Lizenby, Chris Monroe and Vanessa Salas here in Louisville) are a huge help at this point, with standardized photography that lets us take a really close look at those metrics. ![]() ![]() Once a bulb we're testing is done in the lab, we take a close look at things like light spread, tone and color quality. At that point, I plug the sphere's power cord into a variety of dimmer switches, then measure for the average maximum and minimum settings across all of them while also keeping a close lookout for flicker or buzz. We log those brightness measurements every 10 minutes for 90 minutes, then take a final reading at the end. Instead, the bulb's light bounces around inside, which lets our spectrometer take reliable, calibrated measurements for things like brightness and color temperature. Our spectrometer peeks in through a tiny hole in the side of the sphere, with a "baffle" that blocks it from looking directly at the light bulb. We load each bulb we test into the center of our integrating sphere - a big, hollow ball with special, reflective paint coating the inside. This is one of numerous LED buying guides and roundups that I try to update as often as possible.Ī peek inside our integrating sphere. I've also visited and written features about major North American lighting manufacturers such as Cree and GE to get a better understanding of their methods and standards. That includes hundreds of hours in our homemade lighting lab - a climate-controlled room equipped with a spectrometer and an integrating sphere that lets us run the most scientific and accurate light bulb tests we can possibly run. So how do you test light bulbs, anyway?įirst, a little about me: I'm not a lighting engineer, but I've tested and reviewed light bulbs for CNET for over five years now. The best I've tested is still the Lutron Caseta line of smart switches, but keep an eye out this year for new, relatively low-cost smart switches from GE. If you've got a bank of floodlight bulbs overhead that are all wired to one switch, smartening up one switch instead of several bulbs might be the better way to go, anyway. You might need to teach your kids to leave the switch up so your automations will work as planned, but there are new solutions for that age-old problem coming out this year, too.īeyond that, you could always smarten up any of the dumb bulbs recommended in this post by pairing them with a smart switch that's wired into your wall. You won't need to use dimmer switches associated with those light fixtures at all. With bulb-specific dimming hardware built right in, most smart bulbs will dim with flawless, flicker- and buzz-free precision via their app or through some other integration like an Amazon Alexa voice command. ![]() Smart bulbs are a great choice if you're picky about dimming. Those three can all control Sengled and Sylvania bulbs, too, as can other Zigbee controllers like the SmartThings Hub. Hue bulbs require the Philips Hue Bridge, an Amazon Echo Plus or a second-gen Echo Show. Just keep in mind that, except for Lifx bulbs, which communicate using Wi-Fi, all of these smart lights require a Zigbee hub that can translate the bulb's signals into something your router can understand. Payback period (if replacing a matching incandescent)įive, affordable new smart switches will join the C by GE smart lighting lineup this year.
