Unusual LED lamp shape?
Added 2018-12-08 05:33:45 +0000 UTCI'm not sure if these lamps are based on an existing style of lamp or if they are specifically designed to match the beam angle of LEDs for maximum front intensity. It seems to work quite well.

They look good, but as always with these small lighting-festoon style lamps they have a poor power factor which means that the cable and control system sees a much higher current than the load would otherwise indicate. It pretty much means you have to use the same circuit ratings as you did for the same number of traditional tungsten lamps. The LED festoon lamps also pose a slight risk of failing as a dead-short and making tracing a dead lamp in a long string quite tricky.

I've not actually tried a pipe cutter on glass. Fortunately many of the LED lamps are plastic and come apart easily.

2018-12-12 12:26:17 +0000 UTCJust curious, have you ever tried using a pipe cutter to semi non destructively open the bulbs? I know some will even work on glass, rather than shattering bulbs.

2018-12-12 04:05:40 +0000 UTCAh. That makes sense. I will investigate as an exercise. Thanks.
2018-12-09 12:14:39 +0000 UTCMost of the festoon lamps I've seen are ES. I've been trying to find the original order by searching gmail for keywords, but they must be odd because I'm drawing a blank.

2018-12-09 05:23:09 +0000 UTCIf a capacitive dropper powered lamp starts flashing or flickering it's usually an LED that is failing. The bond contact usually makes and breaks with thermal cycling.

2018-12-09 05:10:24 +0000 UTCOk, I’m definitely up to speed on this cap. dropper circuit. I’m learning! I was dictating as you drew it. If you have this circuit and the bulb starts flashing on and off, which component has likely failed? Enjoyed this one. Nice bulbs.
2018-12-09 00:34:49 +0000 UTCThey look really similar to Hue Smart Bulbs, just the end is flatter.
2018-12-08 16:29:51 +0000 UTCThat's not easy to do with modern electronic loads.

2018-12-08 13:54:35 +0000 UTCThe LED filament lamps often have better power factor.

2018-12-08 13:54:09 +0000 UTClook like shot-glasses mounted onto sockets... ^_^
2018-12-08 13:51:51 +0000 UTCI like the style quite a bit.
2018-12-08 13:45:52 +0000 UTCnow i wish to fiend them

2018-12-08 13:08:21 +0000 UTCThanks for another interesting video. Would also be interesting how to centrally correct your house's power factor with an appliance (is there one on the market?) in the main fuse board.
2018-12-08 11:58:28 +0000 UTCI 2nd the call for you try and get as close to a PF of 1
2018-12-08 11:46:50 +0000 UTCAlso, I know you are a night owl but is 05:33 a late night, an early rise or an all nighter for you?

2018-12-08 09:21:15 +0000 UTCHow close to 1.0 do you think you could get the PF by modifying one of these? If you're up for the challenge it doesn't have to fit in the original case but bonus points if it does.

2018-12-08 09:18:35 +0000 UTCClive, did you ever find any LED light with a power factor better then 0.6?

2018-12-08 08:58:35 +0000 UTCVery interesting... any idea what the search terms might be to find these? I wonder if they do a bayonet cap version.
2018-12-08 07:13:40 +0000 UTCLED lamp fatigue? As if! :D

2018-12-08 05:59:52 +0000 UTCI'm not sure how easy it would be to find them on eBay. I just randomly stumbled across them.

2018-12-08 05:52:23 +0000 UTCi kinda want some of those hanging on a string in a line, they could look really neat
