David Geldart of Lumicrest explains the different kinds of socket bases you'll find on lights, from E12 to E40 and the meaning of the names. Lighting made simple!
I can't thank you enough for how straightforward, succinct, & informative this video was. I don't know a single thing related to hardware equipment or anything related to this sort of thing, so sincerely thank you !!
Clear cut, no stories about fishing or having a bad hair day..right to the point and explained to where .... I'm no longer in the dark ...about the many choices when it comes to ordering my light bulbs. Perfect - perfect - perfect! Thanks.. ✍️)))
Thank you so much for this video. Couldn't find any other website or video on the darn internet that explained it as succinctly and as well as you did. FINALLY my search can come to an end.
Thanks so much for this video! Ive been searching the internet to see the difference between the e17 and e12 and no one could answer my question. And I couldn’t find my e17 (now I know what I need) in stores with the daylight! You made online ordering less of a hassle. Thanks again!!
Hello David! Thanks for this. Amazing Edison labs were working in millimeters! You just saved the day on getting through the maze of sockets and bulbs for me!
my mother inherited a torchiere lamp that was brought in 1948 when my great grandparents married. Uses a E39 (mogul) 3 way socket, with a 100-200-300 watt or (uncommon, 50-100-150 watt with mogul base) bulb. Another E39 base bulb you might find in a residential area, is a mercury vapor, metal halide or high pressure sodium fixture in an outdoor floodlight, or if you have an indoor garden and use metal halide/high pressure sodium grow lights.
at 0:51 quote "I dont know why ? but there you go... the bases are measured in millimeters" " Answer :as of 2021 most countries use the metric system. The U.S., Liberia and Myanmar are the only countries left with imperial system.
Yes, the metric system is everywhere! But that's not my point. The reason it seems unusual is twofold: 1) Edison bases have been around for decades, and originated in the US, where metric is not generally used. So it's a little surprising they should be measured in millimeters. 2) Bulbs are measured in eights-of-an-inch in diameter. For example a "par 20" bulb is 20 eights-of-an-inch, or 2.5 inches. So, it's surprising that the bulb diameter is measured using the imperial (inch) system, but the screw base is measured in metric (mm).
Seems the B15D and BA15D refer to the same thing, yes. It's just two different abbreviations for Bayonet (B vs BA) You may also see it abbreviated as BAY
Why can't I find dimmable LED replacement bulbs for my chandelier? When I look at the LED's it tells me their base is an E12, but you can clearly see by looking at the base that it is not an E12. Are E12 and E14 compatible in the same fixture?
E12 and E 14 are not compatible in the same fixture. But E11 and E12 are compatible. One is Euro standard and one is North American but they can be used in the same sockets. As for dimmability there are two challenges with chandelier bulbs 1) They are so small there is very little room for sophisticated electronics in them 2) they consume so little power (like 2-4 watts typically) that many dimmers can't work with them. The issue is that a typical dimmer may not get enough current running through the AC circuit to power itself (because only 2-4 watts is flowing) and the dimmer itself may lose power momentarily, causing flicker. We found the Leviton 6674 dimmer is good for very low loads like this because its internal electronics are designed to run on very low current.
That could be a bit tricky. Putting an E12 into E26 is pretty easy as there are adapters for that, but an E26 to E12 adapter is more rare. If you do find one, the next question is "is it safety certified for North America, such as with cUL or cETL certification?". So you might find one, and it may work, but there's no guarantee it's officially allowed to be used in North America, even though you might buy it in North America... Good luck with it.

I learned much (and I'm 67) from your concise informative explanations. Thank you.
Thank you, Thank you, Thank you! I have always wondered what the size of these smaller bulbs were and now I know. Thanks again!

Good job-Thanks for clearing that up! I am 70 years old and i learned more about socket bases in this video than all the rest of my prior knowing!
thank you! now i know the naming. now I will go on to find wattag differences. thank you so much!!! very straightforward and informative.

Interesting. Hope the video was helpful in figuring that out!
Thanks for clearing all that up!
Thank you!
Fantastic videos! Can you do one explaining about the different voltages?
Thanks a lot
Did not exactly answer my question but I learned so many other useful things

Thanks for the background!
What if your told, a new unbranded nautical tripod lamp fits a E26 bulb, but it’s to big, what now?
Hi I need to find a gigantic screw base meaning I bought a corn cob light for the garage and need a receptacle?
THANK YOU SOOOI MUCH !!!
Great! Thank you
What about the bi pin LED lights? Some connect with pins out where others (similar to christmas light bulbs) fold back on a plastic tab.
Regarding the identification to lamp bases, is the B15d base the same as the BA15d base?
Seems the B15D and BA15D refer to the same thing, yes. It's just two different abbreviations for Bayonet (B vs BA) You may also see it abbreviated as BAY

@@lumicrest Thank you!!!
If there was ever a person that needed less lighting,.
I hate that my Living room ceiling fan Is E17 base. So hard to find bulbs that I want. I'm a fan of the LED Daylight .
How can I fit an E26 bulb into an E12 base?
That could be a bit tricky. Putting an E12 into E26 is pretty easy as there are adapters for that, but an E26 to E12 adapter is more rare. If you do find one, the next question is "is it safety certified for North America, such as with cUL or cETL certification?".

oh boy this guy is really fed up with traditional numbering system of bulbs. lol. very funny. but very informative. thanks
Il manque e 14
it ends early
Lol he's surprised that it is in mm instead of inches, the rest of the world uses mm buddy.
No we don’t use either here on the moon because of the gravity
this odd looking creature.. jesus.. rofl
Thank you!
