Of the 485 lighting listings censused here on 5 September 2026, 482 hold one price across every variant, so most dropdown choices on a downlight cost nothing. What costs money is picking a different listing: a bigger build in the same family adds $3.00 to $4.50, and RGB adds $12.00 to $36.00.
The SL9815 SQ Downlight 16W/6" from SKL-Luce comes in a white or a black frame, and in daylight, warm white or cool white. Six combinations. All six are $48.00, so on this fixture size is the only choice that moves the price.
Size: the millimetre figure is the one that fits
Lighting listings here carry two size figures. The SL9815 publishes Dimension: 150x150mm and separately Size; 6". Both describe the same fixture. The inch number names the family. The millimetre number has to fit your ceiling.
The same model in a smaller build is 120 x 120 mm, sold under its own listing, and there is an RGB version of each size again on its own listing.
| Listing | Size on the listing | Light colour | Price |
|---|---|---|---|
| SL9815 SQ Downlight 12W/4" | 120 x 120 mm | DL / WW / CW | $43.50 |
| SL9815 SQ Downlight 12W/4" RGB | 120 x 120 mm | RGB | $63.00 |
| SL9815 SQ Downlight 16W/6" | 150 x 150 mm | DL / WW / CW | $48.00 |
| SL9815 SQ Downlight 16W/6" RGB | 150 x 150 mm | RGB | $66.00 |
Across five downlight families the step from the smaller build up to the 6 inch build is between $3.00 and $4.50.
| Family | Smaller build | 6 inch build | Step |
|---|---|---|---|
| SL6815 SQ | 4.5 inch, $42.00 | $45.00 | $3.00 |
| SL6817 SQ | 4.5 inch, $42.00 | $45.00 | $3.00 |
| SLCS6817 SQ | 4.5 inch, $60.00 | $63.00 | $3.00 |
| SLC6817 SQ | 4.5 inch, $72.00 | $75.00 | $3.00 |
| SL9815 SQ | 4 inch, $43.50 | $48.00 | $4.50 |
If you are replacing an existing fixture, measure the opening in the ceiling before you order and check it against the Dimension line. Some listings publish the fixture footprint and the opening separately: the SLR1608-1 Spot Down Light is 105 x 105 mm with a 95 mm cut.
One price per listing, almost every time
Of the 485 lighting products live on the site today, 482 carry a single price across every variant on the listing. Whatever you pick from the dropdowns, the price you saw is the price you pay.
Three listings work differently, and all three are magnetic track components priced by length or by power.
| Listing | Price range | What moves it |
|---|---|---|
| SL Magnetic Attraction Track Input Module | $7.50 to $12.00 | module length |
| SL 2400 Recess Type A Magnetic Attraction Track | $20.60 to $65.92 | rail length |
| SL Magnetic Attraction Track Integrated Driver | $23.35 to $38.46 | power rating |
Light colour: daylight, warm white or cool white
DL is daylight, WW is warm white, CW is cool white. On the SL9815 these sit in a dropdown on the product page and all three cost the same. Four listings in the whole range are built that way, and all four are the SL9815 family.
Everywhere else the light colour is stated in the description and built into the listing you pick. That includes RGB, which is always its own listing at a higher price.
| Fixture | Standard | RGB | Step |
|---|---|---|---|
| SL206 RD Panel Downlight 6W/4 inch | $24.00 | $36.00 | $12.00 |
| SL9815 SQ Downlight 16W/6 inch | $48.00 | $66.00 | $18.00 |
| SL9815 SQ Downlight 12W/4 inch | $43.50 | $63.00 | $19.50 |
| SL6815 SQ Downlight 16W/6 inch | $45.00 | $66.00 | $21.00 |
| SL8112 SQ Downlight 12W/5 inch | $36.00 | $60.00 | $24.00 |
| SLC6112 RD Downlight 12W/5 inch | $63.00 | $90.00 | $27.00 |
| SLR836 RD Surface Light 36W/12 inch | $126.00 | $156.00 | $30.00 |
| SLR818 RD Surface Light 18W/8 inch | $87.00 | $123.00 | $36.00 |
The RGB step across downlights and surface lights runs from $12.00 to $36.00, which is several times the cost of going up a size.
Frame finish: free on a dropdown, priced as a listing
The frame is what you see when the light is off. Whether it costs anything depends on how the listing is built.
Where the frame colour is a dropdown, it is free. The SL9815 is $48.00 in white and $48.00 in black. So is the SL1656 Spot Down Light, at $12.00 either way.
Where white and black are separate listings, white costs more. Across the magnetic track range that difference is exactly $9.00 on 21 fittings, and $9.00 per metre on the SLP2398 track rail: $72.00 for a black one metre section against $81.00 for white, and $156.00 against $183.00 at three metres.
| Pair sold as two listings | Black | White | Difference |
|---|---|---|---|
| SLTM1906 Lego magnetic track | $72.00 | $81.00 | $9.00 |
| SLTM1918 Lego magnetic track | $102.00 | $111.00 | $9.00 |
| SLZGB6520 track spot | $144.00 | $153.00 | $9.00 |
| SL71006-A pendant light | $84.00 | $90.00 | $6.00 |
A decorative ring is priced the same way, at $3.00 per light head. The SL661 Spot Down Light shows it cleanly, because the same fixture is sold in one, two and three head versions.
| Fixture | Plain | Gold or rose gold ring | Step |
|---|---|---|---|
| SL1650 RD Spot Down Light | $15.00 | $18.00 | $3.00 |
| SLR1609/1L SQ Down Light | $18.00 | $21.00 | $3.00 |
| SL1209 Spot Down Light | $36.00 | $39.00 | $3.00 |
| SL661 Spot Down Light, 1 head | $19.50 | $22.50 | $3.00 |
| SL661 Spot Down Light, 2 head | $39.00 | $45.00 | $6.00 |
| SL661 Spot Down Light, 3 head | $58.50 | $67.50 | $9.00 |
Reading the listing before you order
| Field on the listing | What it tells you |
|---|---|
| Dimension | The size of the fixture in millimetres. This is the figure that has to fit. |
| Size | The inch shorthand for the family, such as 4 inch or 6 inch. |
| Holder | The lamp type the fixture takes, such as GU10 or MR16. 142 of the 485 live listings publish one. |
| Frame, or Frame Colour | The colour of the housing. |
| Colour Temperature | The colour of the light: DL, WW or CW. |
| Color | On listings with a single colour field, this is the frame. The SLR1609/1L SQ Down Light lists BK, WH and AL for black, white and aluminium. |
What each choice costs
| What you are choosing | What it adds |
|---|---|
| A bigger fixture within the same family | $3.00 to $4.50 |
| Frame colour, where it is a dropdown | nothing |
| Frame colour, where it is a separate listing | $3.00 to $9.00 |
| Daylight, warm white or cool white | nothing |
| RGB, which is always a separate listing | $12.00 to $36.00 |

How much does a downlight cost at ThatRenoStore?
Live lighting prices run from 7.50 for a magnetic track input module up to 1260.00 for an eleven light pendant. The lowest priced light fitting is 12.00, and the SL9815 SQ Downlight in 16W 6 inch is 48.00. Prices were pulled from the live catalogue on 5 September 2026 and can change.
What size downlight should I order?
Read the Dimension line, which is given in millimetres. The SL9815 SQ Downlight is 150 x 150 mm in its 16W 6 inch build and 120 x 120 mm in its 12W 4 inch build. If you are replacing an existing fixture, measure the opening in the ceiling first and check it against that figure, because the inch size is a family name and the millimetre size is the part that has to fit.
What do DL, WW and CW mean on a downlight listing?
DL is daylight, WW is warm white and CW is cool white. On the SL9815 SQ Downlight all three are the same price, so the light colour costs nothing either way. RGB is sold as a separate listing and costs more.
Does a white downlight cost more than a black one?
It depends on how the listing is built. Where the frame colour is a dropdown on one listing, as on the SL9815 SQ Downlight, white and black are both 48.00. Where the two colours are sold as separate listings, white costs more: exactly 9.00 more on 21 magnetic track fittings, and 9.00 per metre on the SLP2398 track rail.
Do ThatRenoStore lighting prices change depending on the options I pick?
On 482 of the 485 live lighting listings, no. One price covers every variant on the listing. The three exceptions are the magnetic track input module at 7.50 to 12.00, the SL 2400 recess track at 20.60 to 65.92 and the integrated driver at 23.35 to 38.46, all of which are priced by length or by power.
