Installation directions lack full description
July 27, 2014
I have called your distributor and she was nice, but lacked the full details to install this light. A complete installation video would have been helpful , but that is not available. I will attempt to have an electrician friend of mine to assist me in this installation. I hope we do not break the lens.
better directions. and a video installation guide would be helpful

T5 Fluorescent
March 12, 2014
This unit was very easy to install. The hardest part is squeezing the unit to free it so that wires can be connected. I used a large offset pliers that provided the proper leverage.

Super Bright Light
November 10, 2013
The replacement of our over-the-sink light went without a hitch, except that the small diameter bulb was difficult to remove and replace using my fat fingers. The light is super bright. My wife is very happy with the result of my efforts. I recommend this product to other do-it-yourselfers.

Great Kitchen Undercabinet Light
May 8, 2013
This was a replacement light for one I purchased just over a year ago from Lowe's. The switch would work only intermittently and Lowe's no longer carries the size I needed. This one fits the bill perfectly. Excellent lighting and just the right size for the undercabinet space I need to illuminate. Very inexpensive compared to others.

Good Value
December 3, 2011
I purchased 11 of these style fixtures in various lengths to redo the under/over cabinet lighting in my kitchen. They were easy to work with and provide more light than I had with the old, larger tube, fluorescents. They seem to be made out of more inexpensive materials than the ones I took out (i.e., thinner metal case), but they work fine and are much cheaper in cost than many similar fixtures. Out of sight, out of mind.

Questions & Answers
By Richard from 04105 on May 20, 2014
Can I purchase this light fixture with a 3000K bulb rather than the specified 4100K bulb?

By Jacob from Pegasus Lighting on May 20, 2014


These fixtures only come with a 4100K lamp.

3000K or other desired color temperature light bulbs may be purchased separately -

By Nancy from Charlotte, NC on August 8, 2012
Can you confirm that these are NOT linkable?
By Pegasus Lighting on August 9, 2012

Nancy, You are correct; these are not linkable.
By Neil from Gainesville, FL on August 9, 2012

I have installed these in my kitchen. They are not linkable if you are thinking of a "plug and play" type thing but the are totally linkable by wire. They have punch out holes in both ends. I ran one power wire into one and then another wire connecting it to the next and then the next. All three are tight against each other. So I guess it depends on what you are looking for, plug together, no; wire together, yes.
By Jim from Concord, NORTH CAROLINA (NC) on August 9, 2012

Well, they are, sort of. You can link them with Romex (this requires a clamp, which Pegasus will sell you). The problem is on the smaller fixtures (12"). There is a switch on one side. The wiring and the switch take up all the extra room, so on the smaller ones, they are theoretically linkable, but in practice, they are not. I ended up going to another supplier to get fixtures without switches. Pegasus might carry unswitched fixtures, or they could special order (but that gets expensive).
By Kevin VanBuren from New Paltz on August 9, 2012

This one is not linkable. See the plug-in linkable one as an alternative.

By Richard from 04105 on May 21, 2014
What size are the electrical knockouts?
By Jacob from Pegasus Lighting on May 22, 2014

They are 1/2inch knockouts.
By CHARALAMBOS from MASPETH, NY on May 22, 2014

They are the small ones. I think around 1/2 inch, if i am not mistaken they come with the connectors.

By Diane from Boston, Massachusetts on September 12, 2012
Can these be installed on a 20-amp circuit?
By Jim from Concord, NC on September 13, 2012

Yes. 20 amps is the limit of the circuit. It constrains how much you can attach to the circuit.

By Mark from Marine, Minnesota on October 21, 2012
Does the 46.25 fixture have a knockout in the back (the side against the cabinet) to hard wire it with Romex?

By Jacob from Pegasus Lighting on October 22, 2012

Yes, each fixture has knockouts on the back of the light fixture.
By Jim from Concord, NORTH CAROLINA (NC) on October 22, 2012


By Shari from Barrie, On, Canada on June 2, 2013
Why does this light have a rocker switch if it is hard wired?
I assume I have to supply the wiring?
By Jacob from Pegasus Lighting on June 3, 2013


The rocker switch is included for those applications where the light is NOT hardwired to a wall switch. Also, it allows you to control each fixture in a circuit individually.

Yes, wiring is NOT included.


By Shari from Barrie,On, Canada on June 3, 2013
Can these fixtures be purchased in Canada, (Ontario) specifically ? If so, where?
By Jacob from Pegasus Lighting on June 3, 2013


We happily ship to Canada. If you'd like to order for us, simply select the size fixture you'd like and click Add to Cart. Feel free to call customer service for ordering assistance.
