Specifications & Measurements

When determining how many LED Very Thin Under Cabinet Lights and which size you will need for under cabinet lighting you first will have to measure the space where the fixtures will be attached. To do this you should NOT measure the face of the cabinets; you should measure the "cavity" under the cabinet where the fixtures will actually be placed. Remember to leave 1in clearance at both ends to plug in power supply cord, connector(s) or end cap. We recommend that you "fill up" the cavity space with as many fixtures that can fit.

Cavity

Perfect solution for under cabinet lighting
October 8, 2013
We had these light bars installed during our kitchen remodel summer 2012. Our contractor was very impressed with them. We have enjoyed them very much over the past year; they have more than exceeded our high expectations.
Pros:
Unobtrusive; provides very good light.
Cons:
Kind of expensive.

Great product!
July 26, 2013
I needed something inconspicuous for my under cabinet lighting, as the cabinet bottoms were not recessed up into the cabinet. These are perfect. They are thin enough not to be seen when I'm standing. When I'm seated and can see them, they're attractive and stylish. The LED lighting is bright, but not overwhelming. I'm very happy with my purchase. My very particular contractor thinks they're awesome.
Pros:
Thin, very attractive design compared to the rope lighting



Questions & Answers
By Glenn from Cape Cod on March 4, 2013
I would like to use this product in a valance above a long mirror. Can I get a twelve foot unit?
By Jacob from Pegasus Lighting on March 4, 2013

Answer:
Glen,

The longest model available is 18-3/8in. You could like together several models with the included in-line connectors to reach your 12ft length.

By Peter from New York, NY on August 10, 2012
Hi.
I need to connect 10 7/8 + 18 3/8 + 18 3/8 + 14 5/8 of very thin light bars in one line from one switch.
What kind and how many drivers and connectors do I need?
By Jacob from Pegasus Lighting on August 10, 2012

Answer:
Peter,

To calculate the driver needed, we simply add the wattage of each fixture. Here are the fixtures you list:
PRULER-3 (10-7/8in) - 3.75 watts
PRULER-5 (18-3/8in) - 6.25 watts
PRULER-5 (18-3/8in) - 6.25 watts
PRULER-4 (14-5/8in) - 5 watts
Total = 21.25 watts

With this many fixtures, you are going to need 2 drivers. I would recommend (2) 12W drivers. You will also need (2) Power Connectors. (Both are available on Accessories tab).

The fixtures include inline connectors, which allow for the fixtures to link directly to each other. If you need to link across a short distance, then I would recommend flexible connectors.

By Scott from Deerfield, IL on August 10, 2012

Answer:
Those 4 fixtures together require more power than 1 driver can supply. I would recommend 2-12w drivers (1 for the 10 7/8" and one 18 3/8", the other driver for the other 18 3/8" and the 14 5/8".) Both drivers can be fed from the same 120v circuit. Switching can be achieved by connecting the driver feed (120v) to your light switch. When I installed my lights, I installed 3 drivers and switched them on one wall switch. I hope this answers your question.

By Matt from Glen Rock, Pennsylvania on December 26, 2012
I need to connect 14 5/8 + 14 5/8 + 18 3/8 + 18 3/8 of very thin light bars in one line from one switch. On the other side of my kitchen I need to connect 14 5/8 + 14 5/8 + 18 3/8 to another switch.

What kind and how many drivers and connectors do I need?
By Ila from Pegasus Lighting on December 28, 2012

Answer:
Matt:

For the first set of 14 5/8 + 14 5/8 + 18 3/8 + 18 3/8...
Since the total wattage is 22.50, it will be necessary to use two drivers, (1) PLED-DR12-350 (http://www.pegasuslighting.com/led-driver-12w-350ma-hardwire.html) for the two 14-5/8in & (1) PLED-DR18-350 (http://www.pegasuslighting.com/led-driver-18w-350ma-hardwire.html) for the two 18-3/8. Generally both drivers can be controlled by one switch.
Will also need (2) Power Connectors PRULER-CONKIT.
(2) Flexible Connectors choice of 6, 12 or 36in.

For the second set - 14 5/8 + 14 5/8 + 18 3/8, Total wattage of 16.25, (1) PLED-DR18-350 Driver can be used + (1) Power Connector (PRULER-CONKIT) + (2) Flexible Connectors, 6, 12 or 36in.

By Rick from Orillia, Ontario on April 2, 2013
I would like to replace a light already wired in with 2 of your power supplies and then run generic wire through the cupboards to the various light strips. Are connectors available to hook to wire?
By Jacob from Pegasus Lighting on April 2, 2013

Answer:
Rick,

The light bars connect to the hardwire drivers using a power connector accessory (available on the Accessories tab).

Then, the drivers connect to line voltage using household wire. Most of the drivers have built in terminal blocks for making this connection.

By Heather from Waterbury, CT on August 12, 2013
Can these light bars also be used effectively for on top of upper cabinets to light above the cabinets area, or are they only good for under mount uses?
By Jacob from Pegasus Lighting on August 13, 2013

Answer:
Yes, they can be used for over cabinet lighting.

By Mark from Greenwich Ct 06830 on April 10, 2013
I would like to install these fixtures but we have installed #14-2 Romex wire to each cabinet location. Can we remote the drivers and will these lights work with a standard magnetic transformer like some LED fixtures do?
By Jacob from Pegasus Lighting on April 11, 2013

Answer:
Mark,

Take a look at the Accessories tab for compatible hardwire drivers that you can remote wire.

I would not recommend using a magnetic transformer because these LEDs need constant current supplied NOT constant voltage.

By CHRIS RAFFETTO from LOS ANGELES, CA on September 20, 2012
Is this available in cool white?
By Jacob from Pegasus Lighting on September 20, 2012

Answer:
Chris,

This item is available in 3100K (warm white) only.

By Chuck from Toledo, OH on April 20, 2013
Is this unit a direct wire or plug in?
By Chris at Pegasus Lighting on April 22, 2013

Answer:
These lights require an LED driver power supply that is ordered separately on the Accessories tab. Each of the LED drivers compatible with this product are hardwire. Thus, I guess you could say that the unit is direct wire. In addition, you will also need to purchase a power connector to connect the LED light bar to the LED driver.

By neal s. fogelhut from encinitas, ca 92024 on April 1, 2014
we are in the process of remodel of our kitchen and want under cabinet lighting. Would this type of lighting be the type we should be looking for. What are the total amount of hardware per light needed as well.
By Jacob from Pegasus Lighting on April 1, 2014

Answer:
Neal, this is an excellent product for under cabinet lighting.

In addition to the light fixtures, you will need a driver, power connector, and flexible connectors for linking the fixtures together. All of these items are available in the Accessories section on the right hand side of the page.
By Rick from Raleigh, NC on April 1, 2014

Answer:
As part of my kitchen remodel, I installed under cabinet LED lighting as well. My lights were hardwired (not plugged in) and all lights were controlled from one LED compatible dimmer switch. I chose the ruler lights to use under a floating shelf that was between two cabinets. I used another brand of LED lighting under the cabinets. The ruler lights were recessed under the bottom of the shelf in a groove so that they were not visible when looking at the shelf straight on. The primary reasons I chose the ruler lights: a. they are very thin and easy to conceal,
b. they operate with a dimmable LED driver, c. the output light temperature (3100K) closely matched the other LED under cabinet lights I was using, d. they can be hardwired in. You will need the ruler lights, a corresponding dimmable LED driver ( which must be hidden inside of a cabinet), a metal box to place the driver in for safety, connection wire from driver to the lights, and a short connection wire to connect the lights together. If you are connecting the lights end to end, then a solid connector is provided with the lights. The ruler lights are very bright on full and can be dimmed down to off. I have not noticed them flickering like you see with other LED under cabinet lights. The lights stay cool to the touch; the LED driver gets a little warm. However, not hot like halogen under cabinet lights. If you are using a dimmer switch to control these or any LED lights, make sure it is compatible. Not all dimmer switches are. I believe mine was a Lutron Diva for LED. You are limited on the number of ruler lights that can be connected to a single driver. There is no on/off switch, so you must have these connected to a wall switch. I am very happy with these lights. Good luck.

By Amy from New York City on January 24, 2013
Hi, I'd like to get 2 of the 18 3/8 inch bars for under cabinet hard wired installation. I will be connecting them. I have no idea which driver would be appropriate. 8, 12 or 15? Also, in the installation example drawings I"m seeing the driver exposed under the cabinet near the light bars. Could I put the driver in the cabinet itself and feed the wire through a hole in the bottom of the cabinet? Let me know thanks,
Amy

By Jacob from Pegasus Lighting on January 25, 2013

Answer:
Amy,


For two 18-3/8in fixtures, you will need a driver rated for more than 12.5 watts, so I would recommend either the 15W driver or the 18W driver.

You can place the driver in the cabinet but it would be wise to check with an electrician to make sure you aren't violating any local electrical codes.


By Catherine Fallis from fallisvc@gmail.com on October 9, 2012
Is this 120v?

By Jacob from Pegasus Lighting on October 9, 2012

Answer:
Catherine,

The drivers that are required for connecting these lights to power are rated for 100 - 240 Volts.
By Rod from Maryland on October 9, 2012

Answer:
Yes, 120 volts A/C is the input.
Output however is 2.8 - 28 volts D/C 350ma.
The variation on output voltage indicates minimum volts for small light strips - up to 28 volts for a sequence of more light strips.

By Sergio from Seattle, WA on December 27, 2013
I would like to connect 2 18" strips and have a hard wire routed to the location that is not connected to a light switch. Are there any 15W or more drivers with built in light switches, or do you have any other suggestions?
By Jacob from Pegasus Lighting on December 29, 2013

Answer:
Sergio,

We do not have any 15W drivers with a built in light switch for this product.

We have similar products that have accessories that allow for switching when a wall switch is available. I would recommend this item - http://www.pegasuslighting.com/led-strip-light-straight-edge-versatile-mount.html

You can use this accessory in conjunction with a driver to switch the lights on/off - http://www.pegasuslighting.com/wiring-box-switch-ptbs.html

By Lane from Denver on October 18, 2012
Is this product approved for closet installation?
By Jacob from Pegasus Lighting on October 18, 2012

Answer:
Lane,

Yes, the light bars will work well in a closet application.
By Todd from Minneapolis on October 18, 2012

Answer:
I purchased these VTLB for a closet but had to return because the power supplies are not up to code for install In the state of Minnesota. They must be enclosed to hide the exposed live household wires, however they are not approved for such enclosed use. Kind of a catch-22. Had to go with another more bulky LED with built in power supply, too bad because the VTLB LED bars themselves were pretty slick.

By Allan Small from Ashburnham, MA on February 12, 2013
I want to install one 18-3/8" light bar with a Pruler power connector, and I'd like it to be dimmable. Since this will be under 7 watts, can I use the 9-Watt 140mA Dimmable Electronic Plug-In Constant Current LED Driver with it - or am I obliged to use the 15 Watt 350 mA dimmable driver?
By Jacob from Pegasus Lighting on February 13, 2013

Answer:
Allan,

The 9W 140mA plug-in driver will NOT work with these fixtures.

The PRuler requires a 350mA constant current driver.

If you want to dim your installation, then you will need to use the 15W 350mA driver.

By Gary from Rochester, NY on January 21, 2014
If I have one run on one switch with more than 18 watts total so I need two power drivers, where do the power drivers connect - to each other and then to the first Ruler strip?
By Jacob from Pegasus Lighting on January 22, 2014

Answer:
Gary,

The drivers connect to line voltage from your home. They do not connect to each other.

Then, the driver connects to the first light bar in the run.

For more than 18W, you will need to have separate runs.
