    Cree Connected LED Bulb Teardown

    This bulb can be remotely controlled via the "Zigbee" protocol. Home depot seems to stock a large collection of remote-controlled bulbs and controllers... it was not particularly clear which, if any, of the controllers work with this bulb, so I just tore it down to see how they added the...

    CREE T8 48" LED Tube Teardown

    My local home depot had a nice selection of LED T8's designed to be a drop-in replacement for a florescent tube (no need to change out the ballast). I bought a CREE and Philips unit. In the tear down video, link below, I took a look at the components inside the CREE design. I has the longest...

    LED Strip lights flickering -

    The driver you have chosen is , by definition, going to produce flicker. PWM = pulse width modulation == turning the LEDs on-and-off with a specific duty cycle. As you have noticed most camera can see this... even increasing the PWM frequency does not solve the problem since you can get an...

    IKEA RYET LED BULB TEARDOWN

    A 400lm bulb for under $2.00 CDN (less than $1.50 USD). That's the cheapest I have ever seen from a vendor with a safety listed bulb. I can't decide if this is a loss leader or if they can make a profit. Retail requires about a 100% markup... which would put the make-cost of the bulb at...

    Sub $10.00 "100w" Philips LED Light Bulb

    Philips appears to returns as a price leader. It's nice to see 100 watt equivalent bulbs showing up on the market. The 60 watt products long ago became very affordable. However, many bulbs in my home are 100W and I could not justify spending upwards of $60.00 to replace those old CFLs. At <...

    Filament LED Long Term Test: 5000 hour datapoint

    Ah, good catch. The axis of the graph should read lux.

    Filament LED Long Term Test: 5000 hour datapoint

    A while back I tore down a filament LED and many questions were raised if the filaments would be reliable. An interesting question. I have had a bulb running continuously for most of this year and it just passed the 5000 hour mark. Video of the results to date, below:

    Sunbeam A19 LED Multipack Teardown

    Another data point in the consumer bulb market. A package of 3 bulbs that were very attractively priced.

    Filament LED

    An interesting question... I put a filament LED into a long term test and the 1st reading suggests the life will be OK. [different source than the Feit, but I presume somewhat similar construction]

    Philips LED "Basic Bulb": so cheap they sell them in pairs

    The consumer market seems to very much prefer lowest-possible-initial cost over almost every other factor. This is probably the definitive bulb. With low power factor and non-dimmable attributes the engineers were really able to squeeze costs. Old-school card board box packaging, a bulb like...

    Philips "Warm Glow" LED Bulb: Adjustable Color Temperatures!

    A rather interesting bulb which goes from 2700K at full brightness down to 2200K: rather novel given that white LED's color is determined by the phosphor at the time of manufacture. A surprisingly simple control circuit as well. Quite a bit of innovation on the go with this bulb!

    Philips SlimStyle "75W" LED Light bulb Teardown

    SemiMan, Brickbat: fair points. Temperature measurements at the die would provide more data. Sadly, the non-warranty is still not very reassuring. "3 hours per day"?! Get home, snap on the lights at 6 pm, but if they are not off by 9 PM the warranty is void. I am still not sure why one would...
