I am starting to goof around with some backlighting - just to illuminate some indicator positions.

I know that it is possible to have a light per indicator, but this is really just to find what button to push at night, not to indicate if is it on or off, so going down the patch of an led strip for everything.

While I was at it, thinking about adding another strip on the outside - just because why not. Then it is there "if needed" with just turning on a switch.

There are some nichia 5000 K agriculture leds that have a fairly flat spectrum and a lot of blue content, supposed to be similar to mid day sunlight. In general I like this kind of light for kitchen use, but I wonder is it the right choice for evening use ? For instance if you need to fix something at night and really see well, will the daylight color be too much, or just help me stay awake better to complete the job ?

Thanks.

I use nothing but 5000K lighting in my house and have no issues with it keeping me awake. IMO it makes things appear more natural, like they would under daylight, instead of biasing colors towards yellow. Or put more succinctly, I like rooms to look the same whether it's day or night.

I prefer CRI over 90. I'm not sure if Nichia's agricultural lights qualify. They're probably designed more to grow plants than for good color rendering.
 
The spectrum is on page 12 of the data sheet. To me, it seems more similar to an HID but it has been a while.

I will also upload a few other of the data sheets for the other versions later today.

We normally use 4000K around the house, I am kind of wondering if it is the right decision for instance for evening lighting, such as camping or working on a car at night or not. I might just end up with both a warmer color and this to have options for either.

Might be CRI 95:

Same part number, and the dual phosphor humps at 530 nm and 615 nm resemble the spectra of other high-CRI LEDs.

Only way to know for sure is to buy it and see how you like it.

This is the light strip I am thinking about. Basically a canned strip light that operates over a wide temperature range and can be used with 24 volt batteries.


I want to buy a canned solution to reduce the amount of effort involved. This can be deal with my needs for both 12 inch and 3 inch strips.

The price is decent enough for what you're getting.
 
Ordered a couple of the 12 inch duos from post #4 in 5000 hort, 3000, 4000 and red.


The 5000K horticulture appears to be similar to the HID spectrum

4000K is what my wife likes.

3000 K is sort of an experiment. What I am imagining is that the 5000K will be good for shadow filling during the daytime, 3000K will be more eye friendly at night, so probably will setup this with the 5000 K hort, each with its own on / off switch. In general I am not a 3000K fan but who knows who will like it or not.

RED - just ordered for fun.

Misc stuff to go with it including the Al channels and covers.

Each strip is 12 inches long and supposed to be ~ equivalent to a 40 -60 watt incan light bulk with 8 watts.

In about a month will try to post some photos and see what it all looks like.

Adds up fast, but still not too bad.
