4.75" Ultra-Thin Square Recessed In-ceiling Light - 6 Watt (45 Watt Equivalent)
aspectLED's Ultra-Thin series of recessed lights are bright, energy efficient, attractively styled, and designed to fit into the tightest of spaces, making them perfect for virtually any residential or commercial application.
At under 1" tall, these recessed can lights can fit into tight spaces that a traditional recessed ceiling light cannot, such as ceilings with ductwork/piping/obstructions, hot-roof ceilings with limited vertical clearance, and tight soffits.
This 6 Watt light puts out the equivalent brightness to a standard incandescent 45 Watt light.
This light now comes with an integrated junction box, allowing you to quickly make your wiring connections without needing to supply your own box, or worrying about whether your box will fit through the cut out hole.
Can Free Can Replacement
Our slimline wafer thin recessed downlights are designed for use as a complete can replacement in normal installations, without the need for a traditional pot, can, or housing. aspectLED low profile downlights have been used in new homes, low ceiling remodels, RVs, boats, soffit and bathroom applications, and more.
Low Profile, Super Shallow Design
aspectLED ultrathin low clearance slim downlights can be used in virtually any location. In most cases, the body of the fixture fits flush with the back side of the sheetrock, allowing the downlight to span directly under joists or ductwork.
IC Rated, UL Listed, Minnesota Based
Our ultra-thin lights are fixtures are IC rated for direct contact with insulation because of their innovative design and advanced thermal management. In addition, our class 2 canless fixtures are backed by a real American company with dedicated customer service and technical support.
Performance and Quality
We work with thousands of electricians worldwide that expect the brightest, highest quality, UL Listed, warrantied fixtures that will perform for years to come. That's why they come to us for all their jobs requiring recessed lighting.

FAQ
Have a question and don't see the answer below? Click here to chat with an LED expert.
- What light color should I choose?
- Warm White is equivalent to a standard incandescent light color and is most popular for residential applications. It has a slight warm yellow glow to it that many people find comfortable and we are all used to seeing in our homes. It is a 2700-3000K on the Kelvin Light Color Scale.
Cool White is equivalent to a standard CFL or Fluorescent light color and is most popular for commercial applications, although it is also used fairly often in residential. It puts out a pure white without any yellow undertone. It is a 4000-4500K on the Kelvin Light Color Scale.
DayWhite™ most closely replicates natural daylight and does have a slight blue hue to the light output. This is rarely seen in residential applications as the light output can seem a bit harsh and bright, and is most commonly seen in exterior or commercial applications. This is the brightest of the White light color options. It is a 6000-6500K on the Kelvin Light Color Scale. - Does this fixture need a housing or a can? How does it affix to my ceiling?
- aspectLED Ultra-Thin lights do not require a can, housing, or box to attach to. They do require an electrical junction box in the ceiling to house the external driver and your wire connection to 120VAC. The light itself inserts directly into your drywall cut out and is held in place by high tension springs.
- How is it installed?
- The light is supplied with an external puck style driver to convert from your power source (120VAC) to the power level the light requires to operate; the driver has a 6” pigtail for you to make your connection to your 120VAC power source. These you would house in a standard electrical handy-box or junction box (immediately above your fixture if you have room). The dimensions of the external driver can be found in the product detail specifications. To finish you simply plug the light into the low voltage side of the driver, and insert the light into your cut out.
- How do I install the Ultra-Thin spring clips?
- We have a video out on our YouTube channel that demonstrates how to install the spring clips: https://www.youtube.com/watch?v=IICADlcO9I4
- What if I don’t have space for a junction box?
- If you are dealing with clearance constraints or limited access, you can locate your junction box, driver, and 120VAC connection up to 100 feet from the light location. By extending the low voltage side of the connection with our 2 foot, 5 foot, 10 foot or 20 foot extension cables, or alternatively, you can use 14 or 16 gauge stranded wire and crimp connectors (select the gauge of wire based on the distance of your run. Always reference a wire gauge chart to determine accurate gauge for your application.
- Can I daisy chain or connect multiple lights together?
- Yes, just make sure that your wire gauge is adequate to support the distance you are running from your power source to the lights and the number of lights on your circuit.
- How long is the wire pigtail length on a recessed light?
- There is approximately 9" of wire lead between the fixture and it's external LED driver. There is approximately 6" of wire lead from the input side of the driver that you can use to connect to your input wiring.
- Can I have multiple Ultra-Thin lights on a single driver?
- Each Ultra-Thin requires its own driver to operate correctly. To achieve the low profile; key components have been transferred from the light fixture to the driver unit. The light cannot function without its individual driver.
- Does aspectLED recommend a particular dimmer switch for use with this fixture?
- Yes, we recommend the following dimmer switches:
Lutron Skylark SELV-300P
Lutron Diva DVELV-300P
Lutron Maestro MAELV-600
Lutron Caseta ELV+
Leviton Super slide 6631
Leviton Super slide VP106
Leviton super slide VP105-1
Leviton Vizia VRE06-1LZ
Eaton-Cooper AL Series - Is this fixture IC rated?
- aspectLED’s recessed in ceiling light fixtures give off low heat when compared to an incandescent fixture; they are IC rated for direct contact with insulation, and are also approved for damp environments like showers and bathrooms.
- Is this fixture UL listed?
- The entire Ultra-Thin product line is UL and cULus listed.
