The Dubai Lamp
<< < (5/13) > >>
Twoflower:
It seems that, at least in Germany, Philips offer similar lamps: LED CLA 75W A70 E27 3000K CL UE SRT4. Unfortunately only 75W and 100W equivalent. Even slightly better: 210Lumen/W; the Dubai Lamp has only 200Lumen/W. Probably due to improved manufacturing processes rather than technical changes.

One could wonder if the updated energy label finally nudges the industry to more efficient gadgets. I would count that a success.

And sorry about the Necro-Post. But I think this time it make sense.

Are you sure ?

Via your link, it seems to let me find, 40W and 60W equivalent, ultra efficient, very long life ones, as well.
Only 2.3W consumption for the 40W equivalent one, and 50,000 hour life expectancy.

You`re right! I sorted the overview to see the latest products and they didn't showed up. It seems the lower-power ones are listed longer as they show up on page 2.

Its a way to pad his income, he is an absolute ruler, after all. Absolute rulers get what they want,  all sorts of outrageous stuff that would never happen  elsewhere. Its like the way colonial powers used to treat their colonies. They were widely thought of as a vehicle for the generation of profit for the sovereign's own purse. Or in some cases, worldly pleasures.

Like, for example, look up "kippumjo" Its so outrageous that most people don't believe it could possibly be for real, but it is. One has to go pretty far back into history, or into really cruel dictatorships,  to find such behaviors in many Western countries.

It has very little to do with actual "improving efficiency" or saving energy costs domestically. This is all about world-stage positioning and marketing of the city. As bigclivedotcom mentions, the lamp was produced as part of a collaboration...

"Philips and Dubai developed the LED bulb under the patronage of Sheikh Mohammed bin Rashid Al Maktoum, Prime Minister of the UAE and Ruler of Dubai. The new Philips Dubai Lamp delivers 200 lm/W, making it the first commercially available lamp to break the 200-lm/W barrier".

So what I think it going on here is, Dubai invested in a venture with Philips and wants to recoup that investment, show an example of technological innovation, spur on national pride, diversify the economy, and promote young people to get into tech industry, among other things. By forcing every new building to buy the lamp they can scale up manufacturing of their venture, perhaps lower the cost and eventually profit on global sales once the price is low enough. How much of the tech in the lamps is actually Philips and how much did Dubai help in terms of their domestic scientific talent, I don't know. Given they say "under the patronage of", it seems to me that Dubai talked to Philips about their R&D targets and made a deal to bank-roll them for some exclusivity deal that would meet their political ideological agenda.

That agenda is Dubai as a forward-thinking futuristic city that is green and efficient. Although the entire region is backed by oil, cities within these countries are trying to diversify their economies into tech, financial, tourism, real estate and so on, and escape from a reliance on oil, which will stabilize the regions long-term, raise up the middle class, improve education and so on.

If they really are more efficient and require less in the way of energy when run that way, they sound more desirable to have. I must confess I went looking for them. I wanted to check one out. I have one location where bulbs seem to burn out faster and I'm curious if some different kind of bulb would also, if put there. I would like to be able to buy an extremely long life lamp, one that lasted years or decades without replacement. Suppose it was difficult to replace, say, required ascending a long ladder or whatever. (I know that must happen in Dubai, land of the large skyscrapers)

Yes, easily missed. I already knew about them, so I had a determined look (and knew a suitable search term for the search box). Thanks, I didn't realize they did 75W and 100W equivalent, ultra efficient, super long life LED lights.

Here is a leaflet and advertising webpage, about the Philips ultra efficient LED bulbs:
https://www.lighting.philips.co.uk/consumer/ultra-efficient

Apparently (  source probably this:  https://www.electronicsweekly.com/blogs/led-luminaries/philips-goes-210-lm-w-bulbs-fanfare-done-earlier-2021-08/  but I may have read a number of websites, so it could be elsewhere  ), the EU new regulations, as regards the efficiency labeling, is rumored to have persuaded Philips to release these new LED ultra efficient ranges.

They seem to be available for sale in the UK, e.g. John Lewis. But are rather pricey at around £12 for the 60 Watt equivalent ones (  https://www.johnlewis.com/philips-60w-e27-led-non-dimmable-classic-bulb-clear/p6040141  ). Also, some express concern it is a 3000K colour temperature, rather than the warm white 2700K ones, that you normally get.
