A quilt member bought a Stella light. It didn't last but one week after the two year warranty. That makes me hesitant about it. I have an Ott fold away desk lamp bought back when they first came out, decades ago and still using the same bulb! I have had to replace the bulb in one of the light bars but it was free to replace as it didn't last as long as it said would. So far no problem and they are about 4 years old now. I went ahead and bought replacement bulbs to have. They will only get more expensive so why not.
The customer service at SMP has been very good.
