I ordered this tube bulb to use with the Verilux floor lamp for a spare bulb. This bulb is not a product from the Verilux company, even though the description claimed it would fit. The bulb looks as if it fits, but it can not be inserted all the way into the socket.
The lamp that this goes with is great, but the color temperature of this bulb is awful unless you like a morbid glow. Of course, this is a matter of taste, but I much prefer a warm bulb of a color temperature of around 2700K or 3000K. The temperature of this bulb is 6500K. I suggest looking for a 4-PIN Compact fluorescent 27W Warm-White bulb to go with the Trademark Home Lamp. You will bask in the glow.
I paid top dollar for this so-called brand name replacement bulb. It worked well whilst it lasted. Unfortunately, it lasted only 8 months. After 6 months, the bulb was not shining as bright as before. For $17.49, a brand name bulb should have performed better and lasted longer than this one did. It is good that the price has now reduced by about 50%..
I use these lamps, which I also purchased from Overstock, and I keep some extra 'bulbs' on hand. I have never had any problems with lamps or the replacement bulbs. I keep a lamp by my reading chair, my bedside, my sewing table... and the lamps can be on for hours at a time.
The light bulbs came broken for the first delivery, and the manufacture did not want to replace it; Overstock customer service person was very nice & resolved this issue for me. So, the customer service in Overstock is impressive & wins my loyalty.
