Philips LED 417097 Energy Saver Compact Fluorescent T2 Twister (A21 Replacement) Household Light Bulb: 2700-Kelvin, 23-Watt (100-Watt Equivalent), E26 Medium Screw Base, Soft White, 4-Pack

I bought exactly same package in home depot about 2 years ago. I didn't expect those bulbs to be useful because they are only 550 lumen; however, they have been very nice replacement bulb for kitchen and bath room lights. The bulb is small enough so it can fit to any light fixture. also it is not too bright so good for kitchen and bathroom light, also the bulb uses only 9Watt so it is cooler than other higher lumen lights. When I found this item, I wasn't 100% sure that they are same one that I bought in home depot long time ago because in the item description here it says the bulb is 500 lumen, but the one I bought in home depot was 550 lumen bulbs. I checked a package right after I received it and it appears to be 550 lumen which is identical to the one that I bought long time ago.

This is the bulb I have been looking for. I am going to order a lot of these and replace every bulb in my house. That's how much I love them. These are 1600 lumens each and VERY bright white. I have two in my bathroom and it's hard to describe but the light in there just makes me feel better. These are skewed to the blue end of the spectrum but the don't have a blue tint at all. They are just clean, clear, white light. Much better than any other brand I have ever tried. If you have been looking for a very bright daylight bulb, look no further. One other good thing about these, besides the quality of the light, is the smaller size. These will fit inside more fixtures than the regular size CFL twister bulbs. It's also hard to beat the price of these. I actually prefer LED bulbs but until those drop in price, I will be sticking with these.

Long-Lasting light bulbs are a big plus in my house. Who wants to keep changing light bulbs? These screw in and out easily, are sturdy and last a long time (like years). Great value for the price I paid. THey're sort of an investment, in a way. Pay once and they'll last and last. No complaints at all with these 100-watt bulbs.

I dragged my heels long enough, trying to stick with incandescent bulbs (I know, I know, it's a lost cause). I hated the CFL bulbs I tried when they were first available and have avoided them for years. But while I was a hold-out, they've clearly improved. They are available in brighter varieties, don't take 10 minutes to fully turn on, and aren't necessarily ugly & huge - which is one of the selling points for these particular Philips bulbs. They measure 3.5" end-to-end; the bulb part measures 2.75". They cast a bright, clean light too. I don't believe they're going to last any 7 years or whatever the claim is, but I WILL keep track & see how long they do last. I priced around and a buck a bulb seems reasonable which is what they were at the time of my purchase. Sadly, my first order arrived quite smashed, mercury no doubt freely pinging around - or whatever it is mercury does - the inside of the package, but Amazon sent a replacement very quickly. You go Amazon.

GREAT LITTLE LIGHTS. ONE OF THE 4 LIGHTS IN THE PACKAGE WAS BROKEN, I TOOK THE OTHER THREE OUT OF THE PACKAGE TO KEEP FROM CUTTING MYSELF ON THE LITTLE PIECES OF GLASS. MY FIRST ORDER NEVER SHOWED UP AND THIS ORDER WAS THE REPLACMENT ORDER.

These were recommended by a succulent blog for grow lights, so I went ahead and bought some about a month ago. They give off a nice white light, and they're pretty bright. My succulents especially love them! They definitely weren't getting enough light in my window, but these lights have helped a lot! I'm starting to see a lot of new growth, and they look nice and healthy. Some of my smaller ones have even got a nice purple color starting to show. What's really nice is they come in a pack of four, so theres replacements for when the one I'm using burns out. I have a dome light that I screw the bulb into, which is sometimes left on for 10 hours at a time. The only negative to these is that I have noticed a slight hum/buzz sound when it's on, but honestly after a few minutes I dont even notice it. I'm not sure if its the bulb or the dome I'm using that makes the buzzing sound, but either way it's well worth it to see my plants so happy and healthy. Definitely would buy again.

I like the product

I WAS going to give this item four stars for arriving intact and on time, withholding a star until I saw what kind of longevity they have. Well, considering I got them yesterday, and one has already burned out, I am giving these three stars for now and considering that generous. If any of the other three bulbs burns out in less than 1,000 hours of use I will revise this again down to 1-star. CFL longevity claims are dubious by nature. They say "lasts 9 years" and then you read the fine print and it says "based on 3 hours per day." Well, nobody cycles a CFL on, uses it for precisely three hours, and cycles it off until the next day. I have a couple 23-watt CFLs running in my shop 24/7 for months at a time that I haven't replaced in years. Based on my initial experience with these, it seems likely to me that if I tried that with these bulbs that they'd all be burned out within a week. Not a money saver at that rate, and not good for the environment to have an item that uses mercury that has to be replaced frequently. When I read other people's reviews about bulbs burning out quickly, I always wonder about the fixture people were using it in. Were they using one of these on a dimmer switch when these bulbs aren't designed for a dimmer? Did their fixture have a loose connection that was making the bulb flicker and putting undue stress on the bulb? Well, I can tell you I was not trying to use these on a dimmer, and I do not feel my light fixture has a loose connection. As to my use, I am experimenting with a small grow box in which I'd like to try to grow tomatoes year-round because store-bought tomatoes are so flavorless. I was hoping to do this with 100 watts or less of CFL power. I have read that plants respond well to the 6500K range of the light spectrum and that is what these bulbs are and why I got them. (Flowering/fruiting plants prefer more red light like a 2700K bulb, but I am not to flowering/fruiting stage yet, so sticking with these bluish 6500K bulbs for now) I will have to see what the plants respond to, but I am starting with a 12 hours on, 12 hours off light schedule. I try to cycle individual bulbs in the box off for one hour during the 12-hour cycle to allow them a cool down period. The grow box has been staying about 80F inside. The bulb that burned out was working when I cycled it off to cool down, but when it was time to turn it back on it no longer worked. I hope this was just a fluke and a defective bulb and the other three bulbs last a lot long time, but having a bulb burn out in less than 24 hours of use is not very encouraging. In terms of alternatives, I also found 23-watt 6500K CFL bulbs at my local BiMart store. They are FEIT brand "Ecobulb Daylight" bulbs. Those are $3.49 each right now, which I believe is a sale price, and they are normally $3.99 at BiMart. Compared to $13 for four of these Phillips bulbs here on Amazon ($3.25/bulb). Obviously I would much rather pay $3.50 or $4 for a bulb that lasts for months or years than pay $3.25 per bulb for a bulb that lasts less than one day. So far I have only tried using two of the Phillips bulbs and one has already burned out. I had been using the FEIT Ecobulbs in the same setup for a week or so with no bulb failures prior to pulling two of them so that I could try these Phillips bulbs side by side.
