Received this replacement bulb. Works great but wish it was 3 or 4 inches longer.
Came quick.

A little spendy, but it was the right light bulb I needed for my OTT light. Thank you for having it!!

The bulb I received was intact and fit my mom's vintage OTT light perfectly. Thank you so much

Bulb for my sewing machine table was no longer available locally. Glad you gave me a source for replacement.

Excellent - thanks for you having such a unusual light replacement

The light bulb fit my lamp perfectly, and had been impossible to find in the local stores. However, my lamp would still not light. I believe that the lamp itself is broken or has worn out, and doubt that there is anything wrong with the bulb.

Received bulb quickly and it worked great.

Ordered 18W bulb. Shipped 13W bulb which is too small. Too short. Prongs too small..

It arrived quickly and worked as described, but was outrageously expensive and with the prohibitively high shipping cost, I would never have purchased through you, if covid19 had not prevented safe purchase in our local store.

Excellent product. Shines a light on my handiwork that is better than sunlight.

my old bulb would not make contact unless I pushed the bulb in or twist the bulb. Your bulb fits perfectly. just use on and off switch and no extras. What a relief. Thank you

This product is wonderful. My reading nook is dark and my Ott light is an essential part of the room for craft work and reading! It creates a true daylight level of light to make the work area useful.

Was a little hard to install but I think that was because of the lamp not the bulb. Great!
