Discussion Overview

The discussion revolves around the potential advancements in 12V LED lighting for domestic use, particularly in the context of creating a pleasant ambiance on boats. Participants explore the quality, efficiency, and pricing of current and upcoming LED technologies.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the possibility of higher power and better color spectrum LED units for domestic use, expressing reluctance to invest in current options due to potential future improvements.
  • Another participant suggests a website offering a variety of LED lamps, noting that many products utilize multiple individual LEDs.
  • There is a mention of LED lamps available in standard light fittings as an alternative option.
  • A participant requests personal opinions on the quality of illumination provided by these lamps, indicating that advertisements do not provide sufficient information.
  • Some lamps come with reviews, including both positive and negative feedback, which may help in selecting suitable options based on personal lighting preferences.
  • It is noted that OLED technology is expected to be replaced by OLET technology, which is projected to be significantly more efficient, although availability may take several years.
  • LED light panels are mentioned as an alternative to compact fluorescent lights, with the ability to vary color output and light temperature, though they are noted to be more expensive.

Areas of Agreement / Disagreement

Participants express a range of opinions regarding the quality and efficiency of current LED options, with no consensus on the best products or technologies available. The discussion remains unresolved regarding the future advancements in LED lighting.

Contextual Notes

Participants highlight the personal nature of lighting preferences, indicating that individual experiences may vary significantly. There is also uncertainty regarding the timeline for the introduction of new technologies like OLETs.

Does anyone have ideas about the possibility of (12V) LED units with higher powers and better colour (/spectrum) for domestic situations?
I am reluctant to pay the high prices they are asking for the present ones if there is a possibility that something much better is on the horizon. This is for use on a boat, rather than in the home but I still would like a pleasant, relaxing, 'ambiance' rather than feeling I'm in some sort of Sci Fi film set.

Greetings Sophiecentaur.

You might like to have a look at this site in Hong Kong.

and many more.

They have hundreds of LED lamps, many using a lot of individual LEDs.
Prices are in US dollars and include postage.

Have a look at their digital scales too.

Thanks for that information but I am really after some personal opinions about the actual quality of the room illumination. Adverts just don't tell you about that.
 
Some of the lamps have reviews attached to them. They seem to publish bad ones as well as good.

The lamps are cheap enough to get a few likely ones to try out. The colour temperature and light output figures in Lumens might give you a clue about which ones to get.
Lighting is pretty personal, so you can judge best what suits you.

I got some balances from them and they were very reliable and honest.
 
It was announced recently that OLEDs will be replaced by OLETs that are x10 more efficient. But by the time they hit the market it will be a few years.
 
There are also LED light panels. Used as ceiling or wall tiles they are a good alternative to CF lights although they are more expensive. They can be varied in output color and light "temperature" from daylight to the softer cooler temps.
They can be powered by AC or a battery that snaps in.
