OttLite T18330 18w Daylight CFL Replacement Tube Bulb, Bulb Type B, Pack of 1

Several years ago, I tried to find a replacement for my Ottlite Daylight gooseneck floor lamp, just to have a spare for when the bulb finally failed. I actually bought a couple of bulbs whose descriptions "promised" they would fit. But, they didn't -- not even close. Even the fabric store where I bought the light couldn't find compatible bulbs. I gave up the search. Luckily, the original bulb lasted more than 20 years (!). But, last week it finally failed, so my search began again. When I saw reviews for this bulb that referred to the OLDER Ottlite lamps, hope returned. This bulb FITS my Ottlite model U203030!!! It requires some careful muscle to push it in (it snaps sharply upon installation), but that's also true for the original bulb. If I could give this product 10 stars, I would.

So happy to find this replacement bulb, thank you!

Great customer service. I ordered an Ott Light fluorescent bulb on Amazon. Bulb shipped on time, no issues there. During the process of replacing the bulb, I noticed the new bulb T18330 did not have the same cutouts in the base, like my old bulb. Picture attached. I tried to contact Ott Light through a number I found on line with no results. I went through the automated Amazon message assistant and got immediate results. I worked with a person named Gina, from Ott Light. She tried her best to answer my questions and resolve my situation. She sent me a new bulb thinking the factory sent the wrong style but basically I ended up with two bulbs that didn’t fit the lamp I was repairing. Gina never gave up though. She told me that one of her supervisors or someone else who had been with Ottlight longer than her was on vacation and would try to come up with a solution for me when she got back. True to her word, Gina got back to me and had learned of a work around which required trimming the matching notches in the bulb receptacle so they didn’t interfere with the new bulb that doesn’t have the notches in its base. I figured as much but didn’t want to alter someone else’s fixture without the company’s, or the owners consent. In the process of trying to find the correct bulb for this particular desk lamp, Amazon and or Ottlight refunded my original purchase price and I still have the extra bulb they sent. I contacted Gina and explained I have two bulbs and have been refunded, she said to keep both bulbs and that they were just happy to resolve the issue with this particular situation. I am always happy to share good experiences with todays customer service. Thanks to Gina, I will consider buying an Ottlight in the future. Thank you Amazon and Gina at Ottlight. Scott M.

The bulb that I purchased came fast and was well packed. However, I must warn purchasers that the bulb may not be the problem if your OTT Lite is not working. It seems that the ballast or transformer on many OTT Lites is not the most reliable component. Afer receiving my bulb and finding out that my lamp was not working with either bulb, the old or the new, I did research on the web and found that the OTT Lite has serious problems with the ballast burning out and being very expensive to replace. I called OTT and found out that they would sell me a new ballast cord assembly, but I would probably need to pay someone to replace it. That part would cost $20 plus labor. They told me that they would sell me another lamp with 20% off. That would cost around $52 or $53. However, it was cheaper on Amazon.com. I did some shopping and found places like Tuesday Morning were selling similar lamps at lower prices still. They had the a fancier Ott Lite for 49.99 with a long 18W bulb and the Verilux Lamp for around $40 on a special sale. Bottom, line, you may not need a bulb, the lamp may be defective not the bulb. However, if you do need a bulb, this company sells a good product at a fair price, and ships very quickly and sends the product extremely well packed. Good seller.

Versatility

I turn off my Ott Lite as soon as I'm finished sewing, so I conserve my light bulbs (I have two Ott Lites). So, I find that these light bulbs last a long, long, time. Since we have recently moved to Florida, I didn't have my usual place to purchase sewing supplies. The large Fabrics store said on their web site that they also had this bulb, however, it was not clear if it was the right one that I needed. What I really like about Amazon, is that it was exactly clear which Ott light bulb I needed for my light. The little sticker on my Ott Lite said to never use a light bulb greater than 18 watts. On the bottom of the base of my Ott Lite it said Model #OLFO18TC. On the chart for this light bulb on Amazon, it gave that number as the Part Number. It gave the Model number of the standing light as #TC10016. This light bulb is called Type B, OLT-18w. So I clicked on Purchase, and the light bulb was delivered to my door in two days. It was easy to change the light bulb. There is a little plastic "door" where the bulb goes in, that you pull down, and then you just pull out the old light bulb, and then push in the new light bulb, and then close the little plastic "door" flap. Thank you, Amazon, for having this, and thank you for the clear directions on which Ott Lites use this particular light bulb. Full spectrum light really makes a difference, if you have never tried it.

I have an OTT Floor lamp that I use when I needlepoint. It is over 30 yrs old. Last week the original bulb finally came to its end of life I ordered a new one based on the description, bc with the original being so old, the identification numbers were different. It fit perfectly and was easily changed. I am looking forward to the next 30 yrs.

This bulb fits my Ott-Lite Crane Desk Lamp. It lights up. There is nothing remarkable about it. So it gets three stars because-- it's okay. My Crane lamp is at least six or seven. It's had the original bulb all that time, seeing daily use.The only reason I had to replace it now was pilot error. I forgot to turn it off so it ran for about 11 hours straight and I believe it suffered heat stroke. It wasn't easy finding a replacement bulb. The original bulb, 18W, made in Thailand, was U-shaped like the current 13W Ott bulb, but has a four-prong notched base. The package states "18W" and "508 Technology". The 13W bulb will not fit this lamp. The current version of the replacement bulb has four basic differences: •Two parallel tubes instead of one U-shaped tube •Non-notched base •Warmer color temperature •Made in China Because of the two-tubes I wasn't sure that this was the right bulb though reviews said it was. And since some of the reviews complained of short life I ordered two. The old bulb had a notch on each side of the base that lined up with two protrusions in the lamp's socket. I think this was to make the bulb a proprietary item. At some point this changed. New bulbs don't have the notches in the base and won't fit in the older socket without minor modification. Using long-nose pliers, it was easy to snap the little walls that formed the protrusions and twist them out. Using a sharp-edged flat screwdriver as a tiny chisel removed most of the rest of the walls. One reviewer used a Dremel tool which is a cleaner method. The new bulb fit well enough into the modified base. Once the pins were aligned with the holes in the socket, mild pressure snapped the bulb into place with a "click". Without modifying the socket the bulb will *not* fit. Let there be light. And there was. The bulb has a slightly lower color temperature than the original so the light is very white instead of the slightly blue cast of the original. I prefer the previous, cooler light, but I can live with this. Being made in China is a wild card at this point. Some high quality products are manufactured there, as is a lot of junk. I have no idea where this lamp falls in that spectrum so it's wait and see. This bulb works in the Crane lamp with an easy, minor modification. No magic, no glamor, three stars.

After a long time looking for replacement bulbs I finally found the one I need .

works perfectly in my Ott Lite lamp

This the second time I've ordered these bulbs from Amazon. I like to have extras just in case. The bulbs are as described, work great in my lamp and sold at a decent price. And the packaging to ensure they arrive safe & sound is exceptional. To the person who said the bulb they purchased did not work, I would suggest that he/she put the bulb on the wrong side (I did this the first time & flipped it over and it worked fine) or he/she ordered the wrong bulb - each lamp has its own size bulb so it can be a bit confusing. So I always do a check and re-check before ordering.

Arrived promptly and fitted perfectly. My out lite is ,many years old and hoped this would fit, now as good as new. Thank you.

Reordered.
