Hi.

What light would be suitable to replace this with, in an LED. Doesn't need to be a straight downlight, we like the diffused nature of that type of light, but the bulbs are a pain to get (long halogens I think) and the bugs get stuck in the "bowl" quite a lot of the time. As they are heavily used lights, LED would be cheaper to run by some margin too.

When I think about it, rather than replace the entire fitting, could just replace the bulb with an LED alternative I guess.

These are the bulbs they take. Looks like 5600 Lumens, which seems incredible?

That's because its a Halogen not LED...

So how do I work out what kind of LED would produce the "equivalent" amount of light?

To get 5600 lumens out of a LED you will be looking at 50/60watt.. but must should have the lumen output spec'd as well as the watt input...

Lumens.

You could probably get away with slightly lower lumens as the LED button lights tend to put out a more even light. Colour temperature also makes a difference. If you go for a cool white (~4000K), it will seem brighter.

Cool white in the lounge wouldn't be ideal I don't think.

You can get replacement LED bulbs for those lights: https://light.nz/light_bulbs/?SubCategory=60 (I have no experience with them)

Do you run the lights on dimmers? 5600 lumens seems like a heck of a lot of light to be coming through (The diffuser will cut some of the light, but I wouldn't have thought by much!)

Personally, I'd probably replace the whole fitting - getting one that won't allow the bugs to crawl in! (That is a pain with the bugs dying in it).

5600 lumen is incredible! Is this one light fitting in a huge room? In our lounge we have four similar looking light fittings which also get bugs, but with standard LED bulbs around 800lm each, 3200 lumen. We turn two lights on (no dimmer, two switches) when we want plenty of light (1600 lumen) and four when we want it super bright. Most of the time we use two small lamps with 3.3W Osram lights, total of about 400 lumen and that's plenty when watching TV, reading kindle, etc.

The LED lights wazzageek linked to are 1100 ish and can be had cheaply from ebay, not sure about the quality. I have or had one in a drawer a while back, not sure the size though.

In your place if you have one massive light fitting I'd consider moving to more fittings with lower wattage bulbs, switches or dimmers, and lamps for standard use. LED dimmers can suck if you don't get a light / dimmer pair specifically made to work together, I gave up on LED dimming with my office dimmable LED lights.

For living room lights having the ability to dim the lights and change colour temperature is darn handy. For example, when watching a movie I’ll dim the lights and change them to a warmer tone.

Consider smart bulbs like Lifx, Hue or some of the cheaper ones like Xiaomi. Hue, while expensive does have some really nice looking ceiling lights and Xiaomi have the same that doesn’t require a controller else could always replace the bulbs and be done with it.

Just an idea anyway.

When I wrote lounge, it's not actually the main lounge but a semi room beside the lounge. My main lounge has integrated LED's.

I am wondering if this product description is wrong at 5600 Lumens. It's not as bright as the 4 x 880Lm I have in the main lounge.

Hard to guage properly, as it's diffused light. Changing the fitting means potentially repainting and plastering over the holes, so unless the new and old fitting are a similar size..

I find it strange there isn't just a straight like for like LED replacement. I've never had that before. 50-60w R7s aren't really very common, but the R7s Halogens were all the rage around the time we bought our house.

They dont exist that will fit into those fittings. And as there is no space for a power supply they are some of the most flickery terrible lamps there are, I put some in some old halogen worklights to try to make them cooler - didnt need all the light that dual 500 watt halogens give and they were horrid things.

Bunnings dont sell them anymore but they were probably about the same as a 60w incandesent lamp, but taking photos under them would never work because of the flicker, even using tools was really hard. Perhaps as a carpark light where not subjected to them for a long time they might be acceptable.

There are plenty of pimple/boob style lights at bunnings that would cover up the mark in the paint left by that old one. Some are even wifi and dimmable/CCT adjustable and under $80.

Ok I had a dig around in the cupboard and found a spare bulb. They are R7s 200W Halogens rated for 3000 Lumens. Much more achieveable than the 5600 previously indicated by me.

Does that change if I can just swap the bulbs?

No, heat from an LED of that size would have it cook up instantly to get anywhere near that light output. I got some stupidly large LEDs for the shed since they were on clearance. Theyre 3600 lumens and look at the heat sinking they need to dissipate that. https://www.bunnings.co.nz/osram-36w-3600lm-daylight-high-watt-led-es-globe_p0014392

4000K to 5000K is in the Neutral White range (my preference, especially for torches). CW is above that, usually 5600K and up. What sucks about those high temperature LEDs is that the cheap ones have terrible CRI (colour rendition index). This makes them seem bright, but not very useful bright - I find it hard to even read with those.
