It's always interesting to explore different types of LED lamp to see if they can be hacked for longer life by reducing their power.
This lamp CAN be hacked, but it's not quite as easy as some of the others.
If tacking a standard resistor on in place of the existing surface mount ones, keep in mind that the lead should not touch the metallised lamp coating, and should be shaped to allow the plastic lens to be refitted.
When I said "dooby" it's a reference to the super-efficient Dubai lamps. By decreasing power dissipation of the LEDs the lifespan of these lamps can be increased greatly. At very low power the lamp could last thousands of times longer due to the greatly reduced thermal stress. The LEDs also operate at much higher efficiency when under-run.

    Live or no!

    I’m maybe 3 miles from the nearest Aldi in my part of Florida but 500 miles from the nearest Lidl — which is in northern Georgia. Easy for me to avoid confusion.

    This was a piece of cake. On Philips consumer units, especially the GU5,3 ones, the circuitry is much harder to get at.

    I got completely fed up with no-name GU10 dimmable lamps blowing up and taking out my trailing edge dimmers a few times per year. Took the plunge and paid the extra for brand name lamps and they have now lasted several years (always on minimum brightness in my living room).

    Philips Fluorescent Lamp are Popular lamps on my country, But led lamp made by my country are best rather than crap Chinese crap lamp, it's called Firefly led lamp, She have an ICC and Philippine Standard, Chinese one are fake CE mark, So it's dangerous to use, it not pass on safety standard

    pretty weird that they're still using multi-layer dielectric films for MR16/GU10 dichroic reflectors in the present era since they're….ya know…totally pointless when used with LEDs. The whole reason they were used was to, as briefly alluded to, allow the considerable amounts of IR from the halogen incandescent bulb to pass through but reflect the visible light forward. Completely pointless with a LIGHT emitting diode that produces no IR. It'd be far cheaper, easier and faster just to coat the inside with a thin layer of aluminum instead. In fact, the whole super reflective coating thing is kind of obviated when there isn't a filament at the focus of the parabola and you've replaced it with a flat PCB that has highly directional LEDs. Skip the whole vacuum deposited coating thing all together and just paint the damn thing white on the inside! Weird vestigial design remnants of lighting technologies past persisting into the present…

    I has a dream you and Fran tore each other down and then couldn't find trays for all the quality machine screws.

    Keep in mind that 39 // 1K is as if you use a 39 ohm resistor with 5% precision and get one close to its lowest possible value

  8. Avataaar/Circle Created with python_avatars Shadow_of_STLKR says:

    Is it cheaper to put hundreds of this 0 ohm links instead of making few layouts?

    I found some glass led lamps similar to that kind of and the moment my screwdriver/pry tools touched the glass to pop the top, the glass shattered in my hands lol I instantly put it back in the box and on the shelf they went 😅 they were in clearance for 2 dollars so I got them

    It'd be neat if you could take a look inside a Philips hue bulb

  11. Avataaar/Circle Created with python_avatars Oliver says:

    I think it would be cool if you did a part two where you build the items back but with a twist🤞

  12. Avataaar/Circle Created with python_avatars Simeon Walker says:

    I have these in my kitchen. After a few weeks the lenses fall off. The lamps then fail a few weeks after that. So, not the best as far as I'm concerned!

    Would you be interested in a 90W LEDVANCE/OSRAM LED Streetlight bulb to take apart? It looks like a "corn on the cob" if you know what construction i mean by that. It has a E40 base and a very solid aluminium heatsink. Its heavy as fuck for an LED bulb.

    Really destructive reverse engineering, but what the hell – it happens.
    BTW. I was at some point confused by 390 being 39R rather than 390R, but looking at it as the power of 10 (i.e. 39 x 10^0 = 39 x 1 = 39) helps explain things much better.

    Sorry if I missed it have you done an unboxing / review / reasons why the new "hoppy"? Take care and stay safe, Mike

  16. Avataaar/Circle Created with python_avatars John Reding says:

    Thanks for sharing your knowledge Clive! how are parallel resistors calculated? 39 + 1K equals 37 ohms?

  17. Avataaar/Circle Created with python_avatars AMDRADEONRUBY says:

    Nice lights bulbs videos related ! Clive for ever really interesting as ever
