We do not offer this lamp in a 15 watt option. 25 Watts is lowest watttage avialable for this bulb type
Yes, very easy to install. Took mins.
You might be able to find a different bulb with four prongs, but this one does not have four prongs it only comes in two prong style
I was surprised with the quick shipping.
The information is located in the specifications.It is 160 lumens and 2700K.
Yes - I'm happy to say this was the perfect match for a candle-warmer I bought several years ago (at either Target or Walgreens). Since I couldn't recall where I purchased it, and I hadn't kept the box nor the instructions...and there was no Manufacturer identification on the warmer itself, I took the used bulb with me on my next visit to Home Depot. Even though it wasn't a wattage they kept on-hand, I did find it on their website...an exact duplicate. I paid for it online, had it shipped (for free) to my local Home Depot, and I was able to pick it up at my convenience.
I use it in my wax warmer, kind of like a Scentsy one, but a different brand
