## Description

Review: Great bulbs, can't go wrong with Philips - Great bulbs for a ceiling fan! I have multiple ceiling fans in my house that use A21 bulbs, and was looking for the brightest daylight bulbs I could purchase to install in them. There were some higher lumen bulbs available, but I wanted bulbs with "long" emitters that weren't directional since I have standard 8 foot ceilings and needed some light scatter rather than straight down projection. These bulbs effectively spread light over a wide area and were compatible with all of the open globe fan lights in the house. They are too large to fit into fans that have a glass case over the bulb, so validate the size of the bulbs before installation. Color rendering is very good, and thus far the bulbs have lasted over a year without any issues. The bulbs I used prior to these had issues with flickering when certain appliances were used such as our inverter air conditioner, and after validating the household electrical supply and grounding did not have issues, I decided to try changing to a different light bulb. This light bulb solved the flickering issue, so I'd highly recommend giving these a try if you are experiencing such issues.
Review: Like high def for your eyes - These bulbs have a great CR rating. Really makes colors stand out. You don't know what your missing with a typical LED bulb until you try these. Good value for the money, most cr95 bulbs cost a lot more. No flicker and are compatible with standard sockets.

## Questions & Answers

**Q: How dim can these get quantitatively? Do these go down to 1%, or only 10% or 20% before the next step is just off?**
A: Coming from someone in the industry, retrofit lamp dimming generally has less to do with the bulb and more to do with the dimmer. Some lighting control companies will have a list of products they have tested with their dimmers and how far it will dim down. You can expect with most dimmers 5-15%, higher end dimmers from more reputable companies will probably more consistently get you to 5% maybe to 1%. Electronic low voltage dimmers generally work better with LED's, if you have an older dimmer from the days of incandescent you probable will be looking at 15% and then off.

**Q: What is the difference between "title 20 compliant" and not? They seem identical: same lumens and wattage, but priced wildly differently.**
A: Well, the title 20 compliance is for California only. If you don’t live in California you don’t need to buy them. Besides that’s a six pack. The other one is a four pack and that’s the one I bought. They’re dimmable, warm glow. I really enjoy them, they’re so easy on your eyes. For you I would recommend this one.

**Q: Will bulbs turn off completely when using a dimmer? some led bulbs remain on slightly.**
A: That's more about the dimmer than about the bulb. If the dimmer shuts off completely, the bulb shuts off completely. If the bulb requires more power than the dimmer's lowest setting to put out a meaningful amount of light, then it will appear off. We just use dimmers to adjust light level and use the dimmer switch's switch function to turn on and off.
If I turn the dimmer all the way down, these are still lit softly, that's our specific dimmers (Lutron toggle dimmers).

**Q: Are these suitable for a damp location such as a bathroom?**
A: That’s where mine are. So good, so far!

### ⭐⭐⭐⭐⭐ For Specific Use Cases and People Like Me
*by W***L on June 14, 2023*

Looking for bulbs that are super bright, have a white point close to that of actual daylight, and have decently accurate color rendering? This is it! First, they're bright. 1600 lumens is usually the upper limit of typical light bulbs you find at a store. I definitely recommend using these with some sort of diffusion, such as a lamp shade or filter, as they do not have any diffusion of their own (clear class instead of frosted). You do not want to have a direct line of sight with them. Most bulbs claiming to have a 5000k daylight white point simply have a boosted blue rendering, with very inaccurate rendering otherwise, but these actually look pretty close to true 5000k daylight, which appears slightly greener than typical 5000k bulbs. This is a great thing in my book, but if you like the artificial blue tint of typical 5000k bulbs (which does have its charm), these aren't for you. White point aside, as far as pure color rendering goes, I honestly can only tell an ever-so-slight difference between these and typical 80 CRI LEDs, but I'm not sure if I have a keen eye for that to be honest. I recorded a slo-mo of these lights in 240hz to observe the flicker intensity of these bulbs, and it is one of the mildest I've ever seen (a good thing). I only use them without a dimmer, so YMMV. I turned on one of these bulbs in one corner of the room, a regular (not ultra definition) philips non-dimmable bulb in another corner, a great value (walmart brand) non-dimmabe bulb in another corner, and a shop light in the last corner. I then recorded a slo-mo in 240hz and turned to focus on each one. The shop light flickered so intensely, the camera's auto-exposure was going haywire. The great value bulb also flickered pretty intensely, but not as bad. The normal philips bulb flickered much less, about have as much. Finally, this bulb flickered slightly less than the normal philips, the least of all of them. (They're all 1600 lumens. I swapped the bulbs in the lamps and repeated the process and the results were the same.) I can't install reccessed can lighting in my room, so I put these in floor lamps to illuminate my home work space, and they do the job wonderfully.
