Review: Great replacement bulb, however, READ ALL OF THE FINE PRINT ON YOUR LIGHT FIXTURE - The light is used by my 98-year-old mother, to read, in conjunction with the mounted magnifying glass; it was imperative that it be replaced quickly as she had used it for over seven years... I suggest that a prospective buyer read ALL of the instructions on the desertcart posting for this, or ANY OttLite product. In truth, I had to revisit my mother's light fixture three times to FINALLY find the model number that fell into one of the long lists of model numbers for specific replacement bulbs. Then I ordered the designated bulb to see if it fit, and it did. Now I've ordered a second bulb so that there will be no lapse in use in the future. Otherwise, no issues; the bulb works as advertised.
Review: It's necessary for a clear view! - I've used the Ott light for many years. It is invaluable for close work.

## Questions & Answers

**Q: I need to replace an Ott-Lite True Color OLT-18 watt bulb, #0605   is this the correct bulb?**
A: Your best bet to make sure that you are ordering the correct bulb is to call the Ott-Lite company. 1-800-842-8848.  You can also visit their website at www.ott-lite.com.  A customer service representative can assist you in figuring out the best replacement bulb. Once you have that information you can then shop online for the best deal.  Hope this helps.

**Q: How can I purchase one--it's only markings are 9209 and True color OLT-18W which does not match anything I can find on line? thank you?**
A: The bulb at the following link is the only 18 watt twin tube bulb that Ott makes:http://www.amazon.com/OTT-LITE-Watt-Pin-Replacement-Bulb/dp/B000EMCRP0/ref=cm_cd_al_qh_dp_i

**Q: Is this a TrueColor bulb?**
A: The description calls it a "daylight" bulb.  In terms of color temperature, that would mean that there is no shift in the color spectrum as you would have if your were reading under a florescent bulb.  If you are planning to use your Ott-Lite as photo lighting, I feel that you would be happy with your photos.

**Q: I have a floor model ott lamp, model fl-18 (on the base of the lamp) and i need an 18w four prong light bulb replacement. what is the bulb order #?**
A: I did not have a model number.....I just bought an 18 four prong.....and it fits just fine.....

### ⭐⭐⭐⭐⭐ Great replacement bulb, however, READ ALL OF THE FINE PRINT ON YOUR LIGHT FIXTURE
*by G***. on September 1, 2024*

The light is used by my 98-year-old mother, to read, in conjunction with the mounted magnifying glass; it was imperative that it be replaced quickly as she had used it for over seven years... I suggest that a prospective buyer read ALL of the instructions on the Amazon posting for this, or ANY OttLite product. In truth, I had to revisit my mother's light fixture three times to FINALLY find the model number that fell into one of the long lists of model numbers for specific replacement bulbs.

### ⭐⭐⭐⭐⭐ It's necessary for a clear view!
*by C***D on September 17, 2025*

I've used the Ott light for many years. It is invaluable for close work.

### ⭐⭐⭐⭐⭐ Fits the older OttLite floor lamp!!!
*by C***E on January 10, 2025*

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.
