richms: I would at least get cool white-warm white strips. aliexpress for that is really cheap, and you can get the "wifi" controller which has a remote for stuff all as well.

That way you can get the exact effect you are looking for and not be stuck with whatever one you buy. the neutral white 4000k is quite rare in LED strip - its mostly warm white or daylight, so the variable stuff means you can get what you want and can warm it up if that is a problem for SWMBO.



Yep, I was taking a look (primarily on eBay - but assume it's essentially similar stock to what's on Aliexpress) and saw the mixed cool/warm white strips. Inded I came across one that did all three (cold/warm/neutral; but it had only 300 LEDs over the 5m). My concern, though, was based on an assumption that these bi-/tri-'coloured' strips would function by only displaying the relevant LEDs (eg, if bi-coloured, when set to 'cool' only half the LEDs would be operating). Is this incorrect, in that are they remote-adjustable to work with both 'colours' and the exact balance can be more finely set between 'cool' and 'warm'?

My concern if only a proportion of LEDs are operating is that the sources of light would be fewer and farther between, therefore need to be brighter to get the same overall brightness and therefore more likely to be noticed as individual points.

I see some of the LED strip lights can come in fairly high densities compared to the normal 300 over 5m, but I understand the other key variance is the brightness of the specific LED type. I'm thinking of going for one with at least 600 LEDs to ensure minimising the source showing - would this be adequate or should I go for 1200? I imagine the ideal would be such a high density with a mix of cool and warm LEDs, with the ability to 'mix' the ratio of the two - is this something that's available?

Also, any advice as to the best LED size ? Am I best say with 3014 (600), 3528 (600 or 1200), or 5050 (600)? I'm planning on using a dimmer, so can control the brightness with that (I'm more concerned with an even lighting).

Many thanks for your advice!

The 5050 mixed cool/warm white have 3 chips with a mix of phosphorus over them light all 3 and you get slightly cool side of neutral white.

Unfortunately the rf controllers only have 2 outputs so what I did was put 2 of the led strings into one output since I never want it all the way to the daylight end of the scale I run daylight and the middle chips off the cold output which then fades over to warm on the other output. Light output drops on warm but that's usually what you want anyway.

I would route a slot into the shelves to take the acrylic so no shadows. I don't even think using clear acrylic as the part holding it would get it free of any artifacts
