Wish I purchased more.
I was looking for more black lights for my son's room and found these on sale.  I purchased 4 and mounted them as one chain.  They provide great coverage along a 121" wall with only one cord plugged into a wall power outlet.  The included swivel brackets work great and I mounted them 1" down from the ceiling on a 45 degree tilt.  I wish I would have purchased more at the time given the sale price was under $10 each delivered due to super saver shipping.  I should have purchased 20 of these things!  I want to mount some under cabinets and other areas of the house.  A few reviewers rated the product one star due to shipping issues.  Not fair, the lamps themselves are great.  Thankfully mine arrived safe and sound.  I will say that out of the 4 one bulb is a bit gimpy, not as strong.
Rating: 5 stars
