Sylvania 24683 - F40DSGN50-40 Watt T12 5000K Full Spectrum Fluorescent Light Bulb, 4 Foot Length, (Pack Of 4)

What was once common item ( fluorescent tubes..) are not all that common to find in stores. In urban areas , a hardware store can be hard to get to. Some sellers want you to buy a case, NOT HERE! At one point my apt. building sold them, not any more ( though they did "advise" me that they would get me 2 at $29 EACH..ahem... thank you, but NO!). This seller ships PERFECTLY, and the lights are BRIGHTER then the old ones that I replaced. Bottom line: Do NOT rent a car or take a cab to go get lights, make life EASY and have them shipped, from this sensational vendor -no stress, such ease. At LAST, the kitchen is lit up again! Go for it! In the long run, you will save money, time, and most importantly, STRESS! You will be HAPPY with this choice, and don't get hung up on the price you probably paid 20 years ago, when you last replaced the tubes! You will be amazed by the brighter than bright look!

Perfect match. A little pricey but these are becoming more difficult to find.

I just set up some shelving for some indoor tropical plants. The room is a bedroom with some good light for a few hours in the afternoon. I needed some constant bright light. I bought two of these bulbs and the work beautifully as a continual light source I addition to the natural sun I have. I wouldn't recommend them as a light source by itself in dark rooms, but if they are adding light, they are fine. The light is a neutral color, nog too blue of yellow. She shipping was fast and the bulbs can in one piece.

Pins broke out on all four bulbs when installing them into the fixtures, making them unusable. Will never purchase Sylvania bulbs again and won't purchase bulbs from Amazon again. Paid too much money for these to be unusable junk.

Arrived quickly and just installed. The bulbs came in cardboard sheaths surrounded in bubble wrap. The prongs were encased in protective plastic. All perfect. Just pull out the sheaths and gently remove plastic off the prongs. They fit my 4’ older fixtures perfectly. Had to fiddle and turn a bit to connect correctly, but voila! Light! I previously had 5000K daylight bulbs, but these seem somewhat cooler and brighter. Perhaps mine were aging. I don’t know what the CRI was in my older ones, but happy these are a 90. I am a painter and was having trouble with the lighting in my studio. Anything between 5000K-6000K (color temperature) and 80-100 CRI (color rendering index) is recommended for good studio light. This was much cheaper than ordering fancy studio lighting where you need to change ballasts for T8 lights. And those were $130-40 for 4 lights! Very happy so far.

Using for a grow light to start my tomato plants. Looks good. Easy purchase.

Since I still have a few florescent lights in my closets and laundry room, I was having a difficult time finding the exact 48" replacements I wanted and needed. We used to purchase them at our local hardware stores but most of them are gone now and Home Depot and Lowe's want way too much for them. Since I originally had Sylvanias, I wanted to get Sylvania replacements. The outer packaging was slightly damaged and I was afraid the bulbs were damaged - but that was not the case. The interior packaging was great and there was an extremely small chance that they would have been damaged. The pricing was great and these bulbs were exactly what I wanted.

This was sold as a "1 pack." Most fluorescent bulbs are changed in pairs and sold in pairs, so I (wrongly) assumed that a 1 pack was 2 bulbs. It is not (from this company), as some other reviewers have mentioned. I did not think I needed to read a review for a light bulb, but obviously I did. For the same price, Home Depot sells an actual pair. Since shipping was free, this seemed to be more convenient, but obviously not - I have to go to Home Depot and get the pair, since a single bulb doesn't help.
