Philips 345017 - PL-L 18W/41 - 18 Watt Long Twin-Tube Compact Fluorescent Light Bulb, 4100K

good quality. good price. Works as expected. good bulb. Fit my lamp perfectly. easy to install.

I think this bulb is better quality than the original one that came with the light. Fits fine and is working just fine, too.

If this fits your lamp, it's a good buy. I have three Ott-like lamps; one or two of them may be an Ott. But this product lasts a long time. I use these lamps everyday for hours and I've only had to purchase the bulbs a couple times. I usually buy two to keep one ready in the closet. This style of lamp is very ergonomic: very small footprint, stands on the floor not taking up a table, adjustable to hang over a chair, easy on/off access. These lamps don't fit a decor that I'm aware of. They seem very modern, with slim, clean lines. They don't match my porcelain Chinese lamps from 1920s in decor but they are exceedingly more useful than those beautiful, useless Chinese lamps.

Purchased to replace a bulb in an OTT light. This bulb took a little persuading to fit, but I think that an original wouldn't be much easier to fit. Much more value for the money and just as bright.

My wife was out of town and I was doing a painting project. I needed more light so I used my wife's quilting light. It was going perfectly until I backed up and knocked the lamp over breaking the light bulb. Didn't have a spare, so I looked on Amazon and there was the exact light bulb I needed. Ordered it and got it before my wife came home.

I bought this to replace the bulb in an OttLite brand lamp. I believe it used the equivalent of the OttLite T18330 18w Replacement Tube Bulb, but I can't say for sure, as the old bulb had the OttLite branding, but no part number on it.This bulb was cheaper than the OttLite, or other compatible bulbs available at the big home centers. If the manufacturer's longevity specs can be believed, it is also rated to last a bit longer.The original OttLite bulb is supposed to be a "daylight" bulb, which practically speaking means a high color temperature (around 6500K), though OttLite fails to specify what the temperature is. It's a bit difficult to compare an old end-of-life dim bulb to a new bulb, but this new Philips 4100K bulb does have a different hue compared to the old bulb - less blue/white, but not substantially different. But I think if you want an identical appearance, you should stick with the OttLite T18330, or order a 6500K bulb elsewhere.

My ot-lite lamp has the same insert as this bulb but it has plastic blockers so you have to buy their custom expensive bulbs. I just broke them off with scissors. Now this bulb fits and works fine.

This product used to be advertised as a spare UV bulb for pond clarifier, but it is really NOT an UV bulb. It costed me money and time. It is not economical for me to ship it back, and wish the supplier simply refund me the money without the product being returned but I doubt it since the supplier wants to make more money by false adverting the function of the product.
