https://www.usa.lighting.philips.com/consumer/ultra-efficientThese LED bulbs seem to be a US-market version of their Dubai lamps, they only list three varieties so far, those varieties being: A 60w eq A19 LED filament bulb with a lumen output of 810 while using only 4.5w, with a lumen efficiency of 180. A 100w eq A21 LED filament bulb with a lumen output of 1540 while only using 8.5, with a lumen efficiency of 181. A 65w eq BR30 LED bulb with a lumen output of 650 while only using 4.5w, with a lumen efficiency of 144. All three vanities are available in two colors, soft white (3000K), and daylight (5000K, 6500K for the BR30 LED). The 60w eq A19 LEDs start at $10 for one, or $17 for a two-pack. The 65w eq BR30 at $11 for one, and the 100w eq A21 at $15 for one.

| Specs looks impressive, though statements like 'Average life (at 2.7 hrs/day) 51 year(s)' draw some suspicion...
Interestingly, these are in consumer part of the catalog, but not in the professional, where more regular variants with ~100 lpw efficiency are listed.

| I doubt if they really have these lumen efficacy figures. The Dubai lamp was a BS fraud.

Rich, Coaster junkie!

| The 4.5 watt is interesting?, we sort of already have this here, the 4 watt filament clear candle lamps that are made by Super Trend (branded DIALL) in the UK are given as 450 lumens, but run one next to a genuine 60 watt GLS lamp and you can hardly tell the difference!
I’ve got two running in my coach lights in the garden and their just as bright as the 8 watt SMT versions that were in there before them!
This is one of them and it’s only 4 watts!

Hello Dor, What do you mean by the dubai lamp was a BS fraud? Can you proove that to me? Regarding the US lamps, I think the european versions and the original dubai lamps are higher in efficinecy, but I will recheck my literature. Regarding the advertised life, im curios about that. I know James did some testing and the original dubai lamps performed very good. The high efficiency is achieved by not loading the leds as much as in general lamps and an improved phosphor blend. (Stark simplification) So indeed the LEDs should last longer due to less thermal stress. If it will be enough to achieve the 50 plus years advertised I do not know. Best regards, Alex https://www.lighting-gallery.net/index.php?topic=10613.0 |

| Yeah, it would be nice to see something to back that claim up, otherwise I'm guessing it's just your opinion that you made up.
It's interesting to see 120v versions get introduced. I wonder if they'll show up in Canada too, most but not all lamps bound for the US market eventually get sold in Canada. Another foreign lamp that I want to see get introduced here are the Trueforce Corepro LED HPL lamps. They look a lot better than the corncob HID retrofit lamps used here.

The problem is that one needs a time machine to back up their claims  |

Before I have known about these LED lamps, the most efficient LED screw in lamps had an efficacy of up to just 120 to 130 LPW at the highest. |

I've found a Youtube video of someone who explain how the Dubai LED filament lamps are so efficient: https://www.youtube.com/watch?v=klaJqofCsu4 |

| I recently obtained the European version of the Philips Ultra Efficient LED lamp.
This one has a lumen efficiency of 210 lumens per watt.
I will upload a photo of it shortly.

| Philips probably is bragging a bit. If I remember correctly, a theoretical lpw for 100% efficient monochromatic green lamp at maximum eye sensitivity is about 683 lpw. For a balanced white light the figure for 100% efficient source was just around 200 lpw. (it is now stated 400lpw, probably with some CRI degraded, 251 lpw for truncated 5800K blackbody)

| I seriously wouldn’t mind purchasing one to do some tests with it to check their performance. I’m curious to if these will eventually become the default standard for Philips LEDs if the launch goes well.

| I'd try one of the 100w in one of my outside lights . See how it performs running D2D .
