I originally wrote a very negative review about this item, because the seller accidentally shipped me some low quality unbranded 3500K lamps, rather than these high quality Bell branded 2700K ones. After complaining to the seller, they very kindly sent these replacement lamps at no extra charge, and without requiring me to return the old ones! So I now have twice as many lamps as expected, though the original 3500K ones are not of very much use.
These 2700K are branded Bell lamps, and are of excellent quality, being pretty indistinguishable from equivalent Philips or GE models. They give a nice, bright warm light with good colour rendering, and appear well made. Like most other 2D lamps, they initially come on pretty bright, and don't take long to reach full brightness.
So in conclusion, an excellent product at a very keen price. If you do order these lamps, make sure they really are 2700K ones, and if not, feel free to request replacements. I cannot fault the customer service offered by this seller.
