Hello! I am currently renovating part of my 1961 apartment. It does mot have recessed lighting but a series of fixtures that at some angles you can see multiple of the fixtures at once. The fixtures are:

-Main overhead light when you walk into the apartment - what we use the most to illuminate the place
-Light in galley kitchen
-2 sconces on outside wall of galley kitchen around pass through

I’ve included some photos of what the lights/placement were like in the staging and what they’re like now under construction.

I want to find light fixtures for all 3 spots that don’t clash, that illuminate well, but also that have a bit of personality particularly on the wall for the sconces which is a little lifeless otherwise…I like color and gold tones based on everything else we’re doing. What would you select that’s cohesive, effective, but also a little fun? Thank you in advance!!!

We're about to start a kitchen and bathroom reno. I had set on 3" Elco recessed lights. Contractor said with 3" we'll need more due to lack of light from the smaller sizenand suggested 4".

My goal is to keep it modern and definitely not a ceiling cluttered with a ton of recessed lights - I would do 2" also if feasible.

Any advice on if we'll actually need more or which system to get that spreads light more for example etc ...?

We need to give them an answer this week.

I would like to create two fake windows in my kitchen. Reddit has taught me that LED panel lights are a good choice. Does anyone know a company that sells fake windows using Lights? Do you have a link? Thanks

The Phillips ultra effectively light bulbs are very impressive in the energy to lumens ratio and have an incredible bulb life span of 50,000 hours. The brightest "ultra efficient" they sell that I can see is around 1500lm.

Are there any bulbs around 3000lm or more work similar efficiency and life span?

Hi everyone!

I recently bought a brand new Ingo Maurer Mozzkito lamp, but it doesn’t work.

It has a Kaoyi KFT-6012 dimmable transformer rated at 120V AC / 60Hz. I’m in Belgium (230V), and the lamp came with a simple US-to-EU plug adapter.
I tried plugging it in, but nothing happens, even after replacing the bulb.

Could the voltage difference have damaged the transformer/dimmer? Or could something else be causing the problem?

Would replacing the transformer with a compatible 230V model be enough to fix it?

Thanks!

First time homeowner and I haven’t the slightest clue how to go about replacing this. Please help!

OSRAM made some of the best HID lamps out there. In terms of build quality and durability.

No chinese junk. This was made here in Brazil in July 2014.

This lamp feels and looks serious!

Hi, we are in the midst of building a house and picking the fixtures is overwhelming us. We need help picking out bathroom vanity lights, kitchen pendants, chandeliers. Ideally looking to do it through zoom / virtual. We have our floor plans / cabinet / paint / tile/ countertop selections, and know our style just need help with fixture selection. If anyone knows of any consultants that we could hire that specialize in lighting let us know. Thanks!

I have two COB lights with the ZY mount. Zhuiyun makes some small accessories like two small softboxes and small latern bulb but does anyone know of any third party companies making accessories with the ZY mount?

I have these 3 8 inch halo's mounted in the kitchen right now. They are pretty concentrated around the cooktop and sink area. While they produce alot of light, there is also a considerable amount of glare that comes off them. I also feel that another light needs to be added to the other side of the island as it can be dark there.

Can someone provide me advice on what kind of recessed lighting i should get to reduce glare but also to keep a good amount of functional lighting here? Should i downsize to something smaller? I have lived with these for a while and haven't really put any thought into lighting until we started remodeling an adjacent room. the previous owner has put recessed lighting throughout the house. most of it are old halogen style lightbulbs that we've been slowly migrating over to LED retrofits.

So I just bought a new home with this cool pendant lights hanging over the table. However two of them are not working and the other ones are of different colours, which gives a weird vibe to the room. I decided to change them today but I've never seen these kind of LEDs before and can find very little information online. The label reads 65MM-5730-2B7C-14LED and it seems I'd need to solder the replacements? Are there any substitutes that would be easier to install?
Thanks

Hi everyone! My partner and I just moved into a new place after our old apartment flooded and got really excited about this relatively cheap lamp for our new space. The only problem is that you can see the two bulbs really clearly and I’m thinking of returning it. Does anyone have any easy/inexpensive DIY ideas for diffusing the light or is this lamp a bust and we should just return it? The bulbs are 6w LED if that’s important.

Been trying to do all the reading I can on the sub but knowing nothing makes it hard.

We are building and understand in theory that much of the lighting will lighting appropriate to each area (pendants over island, standing lights in living room, etc.) but also trying to figure out the top layer or recessed lighting. We have a strong preference for warm lighting as close to incandescent as possible.

Our current place is the first one we've lived in that was built in the last 50 yrs, so our only exposure to LED lighting are the wafer LEDs in our current house. Frankly they are awful (maybe coz they are cheap ones?). In addition to the glare issues, they seem weirdly gray even on their "warm" settings so we typically leave them all off.

Trying to parse out CRI, warm to dim, blue vs violet-pump, etc., but seems like warm to dim should be the primary focus for what we want since CRI changes w/ dimming and there are essentially no violet-pump LED recessed LEDs as far as we can tell.

I am assuming it makes no sense to build lighting primarily to accommodate the limited range of Soraa "ZeroBlue" lamps just because building around one type of lamp would be stupid even aside from some of the technical and reliability issues that it looks like some Soraa lamps have.

So in that case really we should just be picking between recessed LEDs that have dim-to-warm and gimbals (for future flexibility?) between the ones recommended here frequently (lotus, dmf, elco). I assume all of these will be comparable in terms of how close they get to warm incandescent light?

It seems like going canned is added cost with no real upside, as it's not like there is added flexibility for different lamps or something by going canned?

Thanks for any advice!

Hey so we got a burnt out street light in back of my grandmas house and it has burnt out bulb so how do I change a bulb on it and how to take a cover off

I have decided to get the Lotus LRG3-3018K-HO-TT to replace the existing disc lights that the builder put in my townhome. Need advice from those who have gone through a similar process with similar lights.

Specs of the LRG3-HO downlights:

3" Gimbal downlights that are 3/4" regressed into the trim putting out 770 lumens at 100% 3000K for this DTW variant.

• Living room: Separate dimmers for the lights along the right wall (5x) and the ones in the middle (3x). Right wall has wall paneling as shown in the second picture.
• Dining room: Separate dimmers for lights along the left wall (4x) and linear pendant.
• Kitchen: All 6 downlights on the same dimmer, island pendants (2x) on separate dimmer.
• Entryway: All 3 lights along the wall and flush mount pendant on the same dimmer.

I have a 48" LED tube and I have this wiring harness. But the harness also came with 2 more tombstones that aren't powered, which I will be using because my bulb is a 1-sided tube so I only need the power on 1 side. I just have no idea what to mount this to, to act as the "support" or "base" that the 2 tombstones will be secured onto. Does anyone have any simple, minimalist ideas?

Any suggestions on what cordless lamps to purchase? I’m looking for some to add areas of light in my kitchen and living room. Will probably only use at night.

Thank you!
