Background: My pantry (~ 2' deep, 4' across, 8' tall) consists of a bunch of shelves that are 1/2 the depth of the pantry. It has one of those old white pull chain porcelain fixtures on the ceiling with a bare light bulb. I have an 800 lm LED bulb in it and it satisfactorily illuminates all the shelves. I think the bulb is pretty much omni directional so light bounces all over and given the shelves don't extend the full depth, it allows everything to get illuminated.

Well, that bulb is pretty ugly. I could replace it with a globe fixture, but I wonder if strip lighting would yield something cleaner (plus, it's "cool" and maybe I could use that extra space if the bulb wasn't there).

I'd like to mount the strip on the ceiling just above the door (out of sight). My concern is how directional the lighting is. I don't want to mount multiple strips pointing in different directions because that would probably be too bright (unless I dimmed) and it wouldn't be that "clean". I found one post that mentioned a 140 degree angle coming from the LEDs which I think would be OK, but I think that's without a diffuser. I'm pretty sure I would want a diffuser to avoid shadows (and it should help reduce directionality of the light). However, to use a diffuser, I think I would need a housing/channel. I'm worried the sides of the channel would direct the light too much, unless I can find one with a very low profile (low sides).

I don't want to mount strips down each side--I have stuff hanging off the sides that would block the light.

I thought about strips on the underside of each shelf, but they're so packed with stuff, the lights would be blocked and/or it would reduce storage capability. Also concerned about glare from lights shining directly in my eyes.

Does anyone have any experience with this? I'd like to avoid trial and error.

Thanks,

Jim

  • You should not have to worry much about shadows on a strip because there's many sources of light. If you have curvy shiny things and need to avoid hotspots, you can use a single piece of cheap blinds tacked about a half-inch in front of the strip, or foam packing/wrapping cut to fit. Add more strips if needed, but with tight walls like that, it should be bright and diffuse naturally. – dandavis Nov 7 '19 at 21:54
  • By this statement, "I'd like to mount the strip on the ceiling just above the door (out of sight)." , You do mean inside the cabinet, and the cabinet face has a lip on the top front edge where the strip led or channel can be placed behind? – Programmer66 Apr 7 at 17:06

I just did the same thing a few months ago and it turned out great. I routed a 1/2" channel at the back of the shelves so the bulbs wouldn't be seen. The color of the walls is important as well. You don't want to reflect the light, but you don't want to necessarily absorb all of it. A few coats of a flat or eggshell saturated relatively dark color work well.

Even without a diffuser, the light should spread pretty well. With a diffuser, I would expect it to be fine.

For some time, I had a strip of LED tape used as the light for an under-stairs area. I powered it with a switched 8-battery AA box. The light was at least as even as any bare bulb would have been, probably more even.

(The battery-powered approach was a little dim, probably not good enough for a pantry, but it was easy and didn't require me to figure out any line-voltage wiring :) ).

I don't want to mount multiple strips pointing in different directions because that would probably be too bright

In my experience, "too bright" is not generally going to be a problem with the LED tape. I find the quality of light to be good, but never overwhelming. In any case, you can tailor the installation by choosing LED tape with the appropriate chip density for your needs. Densities of 60, 120, and 240 per meter are readily available.

There are also modest variations in brightness according to the wattage/chip type (e.g. 5050 vs 2835 vs 3528, etc.) but I've found that it's the density that is the most significant factor. The next most significant factor seems to be the color temperature, with higher temperatures being brighter.

That said, a single strip mounted over the door would probably provide sufficient lighting. Assuming you're mounting on or over the top of the door jamb, I recommend using a 45-degree channel for the mount, to aim the light down into the space.

  • Thanks. Interesting about the density. I was planning on looking at the total lumens per foot to make sure I was around 800 lm since that seems to be right. I'm guessing that is roughly equivalent to density. And I did notice the 45 degree channels/housings, but wasn't sure about them, vs pointing them straight down. You don't think the 45 degrees would send too much light to the top and back? – Adirondack Jim Nov 8 '19 at 0:26
  • re: lumen/foot...I don't have precise measuring equipment, but I am very skeptical of the manufacturer claims regarding this metric. I have seen wide-ranging numbers for what to my perception are nearly-identical performance. I doubt any of these stated values are measured, and I suspect that if any effort went into producing them at all, it's based on some theoretical calculation, and each manufacturer is doing the calculation differently. The actual chips are manufactured in a reasonably reproducible way, so IMHO the chip type and density are probably the most reliable indicator. – Peter Duniho Nov 8 '19 at 0:56
  • re: mounting...with the diffuser, wherever you mount probably will work "okay". My suggestion about the 45-degree channel is to aim the LEDs down and toward the back of the pantry. This can be achieved whether the back of the strip is against the door jamb/wall, or against the ceiling. You could even mount the strip in the corner where the front wall (with the door) and ceiling meet. – Peter Duniho Nov 8 '19 at 0:58
  • Maybe I'll hold off buying the channel and try pointing down and also at 45 degrees to see which works best. Thanks for your comments Peter. – Adirondack Jim Nov 11 '19 at 21:20

Yes, an LED strip would work, properly size for the 4' width of the pantry and the brightness you want. The LED, located at the front edge of the pantry, should not create any more shadows than the single light bulb. In viewing your objective of a "Clean" look, This would take a lot of effort for the clean look in reviewing all your requirements. The light socket above would have to be converted to an outlet for the LED adapter to plug in, you would still have the issue of the wire running from the "outlet" to the beginning of the LED strip. So you would still see all the wiring for this setup. A "clean" look requires a lot of thought of do you want to pull wires on top of the pantry/ceiling or wiring channel around the edge. Also where would place the power brick, depending on the brand of LED-Power adapter you selected.

If the power adaped is not on the end of the plug, you could put the power brick in the corner, where at 8', it wouldn't be seen. so you only have to deal with seeing the wire from the outlet.
