The MediaLight Quad & Quad XL 6500K CRI 95 (for wall mounts)
July 1, 2020: We have a new range of products called MediaLight Mk2 with CRI ≥ 98 (TLCI 99) and a wider range of sizes. The MediaLight Mk2 costs less on a per-meter and accessory basis than the MediaLight Original with better specs. Please check out The MediaLight Mk2 to see if it is a better fit.
We just introduced a larger Quad called the Quad XL! It's available as an option on this page.
Which version should you get?
Let's look at the perimeters of popular TV screen sizes:
A 65" TV is 14 feet around (screen only, not counting bezel)
A 75" TV is 17 feet around.
An 85" TV is 19.3 feet around.
Original Quad total length: 13.12 feet (4 meters) and includes 122 LEDs
Quad XL total length: 17.25 feet (5.2 meters) and includes 158 LEDs.
(There are 30 LEDs per meter)
If you don't want/need a bottom strip, consider our incredibly slick MediaLight Flex. It's a single 4 meter strip -- no complex wiring or splitters and it will easily cover 3 sides up to 85". Or use it however you want, after all it's the Flex.
Anyway, back to the Quad:
You might have noticed that if you looked merely at the total length, the Quad and Quad XL don't extend around the entire perimeter of a 65" and 85" TV, respectively. Good catch. However, when placed approximately 3 inches from the edge of the display, you reach close enough to the edges to for an even surround (halo).
Still don't know which one to choose? In general, the closer your TV is to the wall, the more you want to run the strips from edge to edge because there's less space for diffusion.
If you are 4-6 inches away, the light will fill in the corners even with the smaller Quad on an 85" TV.
Your ideal Quad size correlates 1:1 to how much OCD you have about wanting the dim surround to be just as bright in the corners of the screen as it is on the sides.
(It's not necessary to extend to the corners evenly for your MediaLight to be effective, but some people clearly prefer it. The Quad XL is the result).
To us, reference usually beats preference in the home theatre debate, but we realised that we could provide both, as long as we wouldn't have to compromise on accuracy. Don't get us wrong, we still don't think that it's necessary to light evenly for bias lighting to be effective (in fact Joe Kane has argued that uneven bias lighting has some advantages), but our customers spoke and we listened. This is the result.
It was very important to us that the Quad and Quad XL be able to run off of the same USB 3.0 (this was the second most-popular feature), so we devised a layout that worked without requiring a 12v adapter (we still include a 5v adapter, or you can use the TV's USB 3.0 port).
