The common lightbulb is about to get a lot more efficient in the US
- iforgotpassword 4y agoThey should also mandate longevity, not just lumens per Watt. LED bulbs could technically live for decades, but there's a trend to drive them so hard that they die a heat death after a few years. And those LED bulbs contain much more electronics and thus stuff that is bad for the environment, so while we obviously save a lot of energy compared to incandescent bulbs, we could easily do even better by not going for the most shitty design that dies early. But I get it, how are you gonna make a living if your bulbs last forever?
- scantis 4y agoThey already try to sell it as a subscription. So you don't pay for the lightbulb itself, but for the service that there is light. It is kind of a ridiculous concept for private customers. There have been some Phillips light bulbs with an app and subscription, that supposedly achieve this. I don't know what happened to it, but was in sheer disbelief, when it was explained to me. There are some other companies, which offer something similar. It may make sense for big installations, that change quite often and I certainly would subscribe to some Christmas led light installation for some time. But having ones home light based on a subscription and not actually owning it, is very strange to me.
- hooverd 4y agoHousing providers could partner with LBaaS providers to provide renters with light bulbs (DRM locked to the unit's sockets for the renters safety of course) for a monthly fee. Hold my NA beer, I've got a great idea for the next YC batch.

- Nasrudith 4y agoIt is admittedly utterly absurd but has some merit. Rental models align incentives better for promoting longevity - they get paid more effectively by making products durable. A hybrid approach of sale of something requiring a subscriptions is the worst existant model as it adds rent while encouraging selling replacements post warranty period.
- eimrine 4y agoAFAIK there are two resistors in parallel on each of those LED bulb, except of in the cheapest ones. If you destroy/unsolder a correct one (with higher resistance), the lamp is going to shine significantly less brightly but with higher energy conversion efficiency and with significantly less heating. If not a correct resistor has been dismounted, the lamp is going to shine too dimly to be useful. PS. I have not tried this livehack yet, so i can not promise it works, but maybe it is important to clarify that my source is talking about 220V bulbs.

- addaon 4y agoI have some of the original Philips L Prize bulbs from ~2012. They've probably been on an average of eight hours a day for more than a decade now. I'm sure brightness has declined a bit, but not noticeably. Otherwise still great. They weren't cheap, but I expect to get another decade or two out of them.
- Grazester 4y agoBought a Philips CFL bulb in 1998. It ended up lasting 12 years. It was bought for a garage that had no door so sort open to moisture when it rained. It would be on sometimes several days if forgotten but on average eight to twelve hours over night. Incandescent light bulbs would blow in a month or two and at 75 watts it cost several dollars a month because energy was not cheap in that country. Philips knows how to make a bulb.
- CincinnatiMan 4y agoIs there an LED bulb that can produce a CRI of 100? I wonder how things will change with there no longer being incandescent or halogen bulbs, which have a CRI of 100. People might think they're putting on a certain color indoors, either clothes or makeup, only to realize it's different when they're outside in the sun haha!
- rdtwo 4y ago100 no but 90-95 is possible but hard to get. 70-80 is standard for consumer grade stuff
- ahartmetz 4y agoIME (Germany), cheap LED bulbs usually have CRI 80 and you can find a few(!) bulbs with CRI 95 in most shops. The are often of the fake filament type, which usually comes with other good properties such as looking nice and not flickering. But you have lower efficiency, not dimmable, few color temperature options, and medium brightness (~80W incandescent equivalent) at best.
- eimrine 4y agoHow about trying MHL instead of LED? AFAIK 120 Lm/W is not a limit for an arc lamp and CRI 100 is possible.
- addaon 4y agoThere are some options that come pretty close: e.g. (no association) https://www.waveformlighting.com/absolute-series https://www.waveformlighting.com/absolute-series
- rayiner 4y agoLED lights have so many shortcomings (weird color spectrum, often flicker, etc). You can do tons of research and find ones without those problems. But instead I’ve just stockpiled incandescent bulbs, particularly for the dimmable lights in my living room.
- Kon-Peki 4y agoThe inexpensive LED bulbs I recently purchased were 94 lumens per watt. A 30% increase is probably already something you can buy, just a bit more expensive and harder to find. This most likely is only going to knock the cheapest bulbs out of the market and make it more likely that Home Depot or Walmart puts the decent stuff on the shelf for people to buy without thinking about it.
