@mbersiam No-- E26 and E12 base (it’s in mm IIRC). ‘regular’ and ‘candallabra’

@mbersiam https://www.bronsondesign.com/blog/what-is-an-e12-or-e26-light-bulb/ Looks like you need E17 ‘intermediate’

@mbersiam You can buy E17 adapters to fit either the larger or smaller bulbs in those sockets, but at about $2/adapter, you’re probably better off just buying the right size

@caffeineguy @SnakeJG Thank you both. I bought my house in July and went to change a couple bulbs in our extra room and found out my bulbs didn’t fit in that particular ceiling fan fixture. and I haven’t been to the hardware store yet to find the right size. I was hoping to just order online but had no idea what to even search to get the right size (hence the photo I took to send to my dad )

@caffeineguy @mbersiam @SnakeJG Ceiling fan – that explains it. To get away from including more expensive LEDs to meet efficiency standards, some fan manufacturers switched to using smaller bulb sockets, which are considered “decorative bulbs” and excluded from the efficiency standards.

@chienfou The design engineer specified components that would result in a 100,000 hour life assuming there was unlimited airflow around the bulb, and the air temperature was a constant 68° Frankenstein/20° Canadian.

The manufacturing engineer substituted components that would give a 25,000 hour life, under the same ideal conditions.

The clerk at the factory ordered parts of dubious origin that look similar to what the manufacturing engineer specified, but were much cheaper. Leading to an unknown life, probably not to exceed 8,000 hours under ideal conditions.

Actual life will be lower if the temperature is higher, or if used in an enclosed fixture.

@chienfou @hamjudo I can verify, I bought these a few years ago and many (60%?) of the BR30s installed in can fixtures have died already. At the outside they could have 10,000 hours? A couple died within the first year, so maybe 2000 hours. They go dim and occasionally one will annoyingly strobe. This is not limited to this brand, I have GE bulbs in bathroom vanities that do the same thing.

I have BR40s of these installed in outdoor floodlight fixtures (open to the air) and have had no problem with them.

The retrofit LED pucks with trim that replace the cans are much better, my guess is that they have lots of metal to dissipate heat and so they last longer. LED bulbs where all the components are inside the bulb body and the bulb goes inside a can or other enclosure don’t have anywhere to let the heat go so they cook instead.

Unfortunately I don’t much feel like tackling the cans in the higher ceiling parts of my home so more bulbs it is. Right now 3 of 4 lights in my bedroom need replacing but having lights on the fan enables me to procrastinate.

@chienfou @djslack Big Clive has made some YouTube videos showing how to convert normal 100 watt equivalent bulbs into 50 watt equivalent bulbs with a reasonable lifetime. Dimming a bulb by a factor of two increases the lifespan by dramatically more than doubling.

Alas, some bulbs are easier to modify than others, the exact details vary greatly, and the only way to know is for someone to dissect a particular model. Big Clive lives on the Isle of Man. He shops at different stores than we do.

The ideal bulbs have thermal management configured so they dim themselves if they get too warm. They never allow themselves to get hot enough to significantly shorten their lives. Such bulbs are known to exist, but seem to only be available in the one middle eastern country that mandates that feature.

@werehatrack I don’t buy bulbs that aren’t 2700K. Anything 3K or higher is too institutional for me.

@chienfou
wow… it’s deja vu all over again…
