OttLite® 18W Replacement Tube is rated 3.8 out of 5 by 54.
Rated 3 out of 5 by from Replacement bulbs! Ottlites are great until you need a Replacement bulb. They make the same wattage bulbs, but the plug-in part won't fit into the older lamps. So, I suggest that when buying a new Ottlite, buy two or more replacement bulbs at the same time. Otherwise, you have to finally just throw out the lamp when the bulb burns out. The lamps themselves are terrific, but, bulb replacement-NOT! I searched everywhere in stores and online. In the future, I'll buy extra bulbs, and try seeing if they fit the lamp right away.

Rated 5 out of 5 by from Great Light I have used this bulb in my Ott lamps (3 of them) for the last 3 years without any problems. I use it to provide "natural" light for my birds and it really helps provide better light to aid their feather condition (color). I have replaced them every year (they burn approx. 10 hours per day) as the effectiveness of the light does diminish as all full spectrum bulbs do. But I have never had a failure. They are expensive so I wait until Jo-Ann has them on sale and then purchase them.

Rated 5 out of 5 by from bulbs last "forever" Rec'd 2 floor Ottlites as gift from my dad 9 yrs ago, bulbs still going strong. Lamps are used daily for all reading, projects and as evening/TV lighting. Have moved 3 times, ,no breakage. The clarity and non-glare is exceptional: I won't read under any other lamp in the house! Am buying another bulb now "just in case"

Rated 2 out of 5 by from Dissatisfied I use my OTT-LITE TRUECOLOR lamp whenever I'm knitting. It helps me to see the stitches easily. I purchased the lamp about 8 months ago. Approximately six months in, the bulb started giving me problems. It worked sometimes and didn't work other times. Now, it's not working at all. Others have experienced the same thing, too. I'm still knitting but lack the proper lighting. OTT-LITE should take responsibility for this inferior product and replace the bulbs. It wasn't worth the expense.

Rated 1 out of 5 by from true color floor lamp bulb I love my ott-lights, I have two, this one I hardly use. It's by my bed and I read sometimes before dozing off. The bulb burned out so quickly that I suspected my husband or son touched it but they didn't so I'm replacing it hoping it's a flaw in the bulb to begin with, my other ott-light is in the family room and is used everyday, it is a floor lamp with a swirl bulb, I really wish I had bought two of those instead of the true color one, At the time of ordering I wasn't sure which one to get so I got both. Maybe this new bulb will last longer and I'll feel more satisfied.

Rated 5 out of 5 by from Seven years; 3rd set of bulbs As I was saying (when I hit the wrong key), my lights stay on for 9 hours in my bird room, and nary a problem. I do know what the problem is for these other ladies, however. When inserting the bulb, you MUST hear it snap into the socket very loudly. If you don't hear that, it isn't in all the way, and will not function correctly. Turns on and off, because it isn't firmly connected in the socket, so it's similar to shorting out. The proof is in the pudding, ladies.

Rated 5 out of 5 by from Wonderful Light Our old Ott lite finally gave out, but lasted over 10 years! This one is certainly made even better in every way since our initial purchase of the prior Ott lite. I used to do some quilting, but never quite got into it fully. My project now is homeschooling a 14 year old in 8th grade, our grand-daughter who lives with us as well as her Mom, who works part-time with Jewel-Osco. We love homeschooling, first time for both she and I. The challenge proved that we have what it takes!! She is getting straight A's and does not miss public schools, whatsoever. She is into making the furry type animals for wearing, and has learned to design her own, after initially purchasing her first one from someone online; so she's almost busy as me!
