I remember actual terrariums and display cabinets like this back in the 70s, so i'd cast a vote in the 'dated' column. (Not to mention, cleaning all the separate little glass areas). There are timeless designs that can kind of cross decorating styles/categories....I'm sure you'll get lots of suggestions.

If this is the light that speaks to you, then by all means get it!! Lighting is a very easily changed item if you decide to sell several years down the road. Never worry about lighting being dated.

I have that style Shaker cabinets and much prefer them as that "edge" does not collect dust. Think about it before ordering...

I put a light like this in my hallway in 1995. Just replaced it. Horrible trying to clean it - it got dusty and always seemed to have a hazy film on it even with glass cleaner. Impossible to clean those little glass panes.

Lighting is SO SO SO easy to change. If this is what you like now, get it and enjoy it for as long as you like it.

That said, if you are deeply concerned with dating your kitchen, all your other choices will be much harder/more expensive to change and are extremely, extremely trendy. Shaker is SUCH a popular cabinet door style right now. Grey and white are SUCH popular colors for everything right now. White counters (especially marble or marble-look-alike) are SO popular right now. Gold/brass hardware is what basically all interior designers have been using for a while now, and I think they're just beginning to move away from. I'm already noticing that people are getting sick of white subway tile (and all the updated variations of them - longer, smaller, etc.), so I think that huge trend is also already leaving the station.

You might think about swapping a couple of these choices - doesn't have to be all or even most by any means - for some things that aren't one of the most popular choices right now.
That would keep your kitchen from looking like a perfect snap shot of this kitchen era down to every single detail, which will make it look less noticeably dated when we're in a different era.

Your choice references art deco. Many fixtures of the period were faceted like this. I think stylistically they are a good fit.

IMO lighting in a kitchen should always be good light and those bulbs are never good light . As for the fixture itself it is just a light if a couple of years from now you don’t like it it is an easy thing to change.To be honest no one knows what will scream dated down the road just do a space you love and forget the next guy that buys the house.

Anything you buy will look “dated” at some point, so just go with what you want. Those lights would drive me crazy though, I’m too OCD , I can’t imagine keeping them clean ...

I think they look awesome! I would love to see an after photo of your kitchen remodel with these. Yes, they might be tougher to keep clean, but you won't know until you get them! I really believe this is an awesome and very now look!

Here are deco fixtures from various public buildings near me. I think you can see the influence.

Or this 1929 Hotpoint ad:

However, note that this one and all of palimpsest's do not have transparent glass.

I don't think your choices are suitable for places where you want a fixture for light, rather than just ambiance. The glare from visible bulb fixtures is pretty awful when they are bright enough to actually cast any light. I would look for something with frosted glass or some kind of shade if these are for working light.

ETA BTW, if anyone ever runs across the opalescent fixture in this post anywhere in real life, please let me know.

First off, many many thanks to everyone who responded for these kind words and insightful comments! Palimpsest, thank you for these photos; I really appreciate them because we do try to be faithful to the overall character of the house when we make changes.

I should have added that another reason we're strongly considering these lights is that the Emtek mod hex hardware (in particular the knob, pictured here) features a hexagon shape; we'd like to pick up on it with the light, if possible.

My question is you have a 1930's house.

Why are you trying to "update" it to today's trends? Basically I'm asking about gray shaker. Shaker is period appropriate for the age of your house but gray is a trend and it's a trend that is on it's way out. When you try and "update" an older house to today's trends, it just winds up looking more dated in a few years than if you paid homage to the house's history.

1930's kitchens were all about color, tile and those "modern" appliances (like those tiny refrigerators). Obviously none of us wants to cook in a 1930's kitchen but why not pay tribute to the style more? Colorful cabinets or soft white cabinets with a colorful backsplash? A nod to Art Deco?

As for the light, have you looked at Rejuvenation for lighting? They have lighting that echo's the period and you can choose your globes and your finishes.

I think the gray would be okay because it was used in deco interiors but I would definitely consider something more colorful for the backsplash. Your grey is subtle enough, I think, not like some of the deeper gray cabinet colors also on trend.

Danette, thank you for this! And yes, that's exactly our approach: we aren't doing a true restoration, just want to more or less hew to the character of the house.

There are so many choices out there. The thing about the pendants being the same shape as the knobs will be hardly noticeable. Also, if you've seen this kind of light on at night, you'll know it casts weird shadows. I'd keep looking for something simpler and more consistent with the age of the home.

One of the things that I will say about these lights is yes, they will cast shadows, and No, they should not be the primary light source

That said, there is not a single ornamental fixture in my house that is the primary light source in any room in the entire house, particularly not in a kitchen or bathroom.

The kitchen and bathrooms are (or will be in the case of the upcoming kitchen) primarily lit from the ceiling by recessed lighting and by task lighting at the counters.

The ornamental ceiling lights I took out of the bedrooms in my parents' house had been turned on so infrequently that the original 45 year old bulbs (all six) were in two of the fixtures. Those rooms were lit primarily by lamps switched by the door.

My assumption regarding these lights by the OP is that the kitchen would primarily be lit by recessed and task lighting and that the pendant lights would be be adding sparkle and some lighting and that the weird shadows they may cast would be obviated by the "real" lighting, recessed or close-to-ceiling and task lighting.
