This is available in India. Manufactured at the Philips factory in Kolkata India. The previous generation bulbs were made in Bangalore. The Bangalore bulbs were expensive and have better finish than these bulbs. The light distribution is better in the Bangalore bulbs. You are right about Philips compromising quality to reduce the sale prices of the bulbs.
I've had one of the lower output versions of this lamp running for almost a year in an outdoor fixture with no dimming. I did pop the globe part off since the fixture is tube shaped and it only needs light in one direction. Hopefully these "100w" versions are a long lasting! Did you get a chance to take any temperature measurements of this lamp?
Looking at this about 2 years after it was made... in comparison with the 8 to 9.5 watt bulbs, nominally 800 lumens or 60W equivalent, I’ve been buying for US$1 at Dollar Tree stores, the circuit is sophisticated. The $1 bulbs have a capacitive dropper, a bridge rectifier, a little filtering, and not much else. Failure rate is pretty high and the ones I’ve taken apart afterwards always seem to have lost a single LED from the series. You get what you pay for?
markiangooley In the cheap bulbs they are probably running the LEDs quite hard to get the desired output out of fewer chips wich doesn‘t go well with sloppy tolerances so eventually one will fail.
Is it dimmable? I have similar bulbs and they are labelled non-dimmable. But they can be dimmed if I add more load to the dimmer. Which component would fail if I were to continue using it with a dimmer?
I'm using these in out door motion sensor fixtures both working fine. No one is into recycling led bulbs, all I'm finding is dispose of them in the trash
You really need a better mic, your deep voice is producing noticeable distortion. Your macro shots are excellent though so clearly you have good video gear.
So the bulb is heat "sinking" 10-15W into a closed compartment containing electrolytics where heat has to be dissipated away through a wall of plastic. The bulb is way overpriced for a design that bad, because I guess the bulb won't last much longer than an incadescent.
Thank you. Good work.

Hi. You didn't mention the power factor. I measured a 220V (100W eq.) version and PF its barely over 0,5. Again, cost cutting seems key here.
I bought a 1600 lumen, 20 watt LED bulb (Polaroid brand) and it reaches 105 deg C on the outside casing. I don't expect it can last very long.

Cheap leds don't need to last long to pay themselves back. Unless you have extremely cheap electricity.
thanks for the review. i think that maybe you can check thr new RYET ikea bulbs lineup it might be with a better build quality?
You should review the Uluxus led bulbs, which look just like an incandescent 60w bulb.
Impressive... but I wonder how long it will last with the heat that surely will be cooking that bulb's insides.
Thumbs up :)

+bruce p don't know if it matters but are you doing the soft white or daylight which mine are
Where did you buy this bulb?
Home Depot
Okay cool thanks
hi, I just read that philips will not make lamps any more. no money there for them will be focus on medical.
+Proyectos LED most of philips is another company leasing the name, so im sure someone will take it on.
