UPSIDE DOWN. One comment and one question. (Page 1/2)
BingB JAN 30, 11:03 AM
First the comment. I just discovered that some lightbulbs should not be used "upside down". That means with the metal screw part up and the glass globe down. It says so right on the back of the cards that the bulbs come on. I just never knew to even look.

Now the question. In the movie "F9: The Fast Saga" after they flipped the truck/train vehicle upside Dom and Letty blow a hole in the bottom (which was now the top) and drop inside. There they monitor the progress of the upload of Aries to the satellite. i was recently told that while they are doing this the computer screens are all right side up instead of upside down like they should have been. I found this hard to believe, but when I went to watch the movie to find out none of the networks that I subscribe to had it for free. It is only $3.99, but it is the principle of the matter. I can't believe that I pay for multiple network memberships and still have to pay to see a movie that has been on free TV for years.

So if anyone has free access to F9 could you let me know. I figure it is the most popular of the series here since it is the one with the Fiero in space.

People actually still watch that F stuff??
The 1st one was bad enough.

Some cheap LED bulbs have electronics in the base that are overly sensitive to heat. Since heat rises, those bulbs have a short lifespan when the LEDs themselves are beneath the electronics.

It is similar, but inverse to the reason that old condenser mics were often hung "upside down". The heat would rise from the preamp and effect the performance of the condenser.

FF1 was all about the "ricer" crowd, which is now a non-PC term. The second one wasn't so great either, as it was still very much focused on the pro-Honda / Toyota crowd.

People took those movies very seriously back then as it being very legitimate to the SoCal racing crowd (so I've been told, I'm from the East Coast). But at some point, they started having a bit more fun with the movies, and making them more "campy," like... how can I explain it, movies like The Expendables. They weren't really to be taken seriously, so much as it just became a cool action movie with a plot / growing character background. When you watch the movies with that frame of mind, they are actually really cool movies. The first couple ones though were for a different crowd of people for a different time. The movies matured with the people watching them.

But it was the time. If you watch the remake of Gone in 60 Seconds with Nicholas Cage... they race a Porsche 911 against a neutron blue Honda Civic SI... and through the ENTIRE race, the Honda Civic is keeping up (if not beating) the Porsche 911. The Porsche 911 only wins because it runs a red light in front of a police car. But the whole race is ridiculous because a ~2000 Honda Civic SI has a 0-60 of low 7s on a good day, and the Porsche 911 has a 0-60 of mid-4s. But they only did that because half the "car crowd" was like HUGELY into those Civics and other 4cyl/FWD imports.

I promise you, I'm much cooler in person... hahaha...

Not just LED bulbs have issues on how their mounted.

True that Many LED "bulbs" make heat that must have a way to remove heat generated by LED themselves + Heat made by whatever else to reduce/regulate power for the LED sets in them. Capacitors & more can cook when LED "bulbs" are Base Up or in enclose fixtures.

But CFL & more have similar problems.

Example: Many Projector bulbs, halogen or not, have specs for base down, up, even sideways because of how their made to keep focus when hot & other issues.
Film projectors, Theater lighting, & thousands more have "rules" how to operate X for this fact + other reasons to keep the bulb & socket happy.

Even for "home use" w/ Long w/ 2 R7S contacts on ends & other Halogen bulbs don't last long if mounted wrong. The long ones want to be mounted Horizontal or filament fails fast often in minutes to seconds when hot. Type Example:

Does anyone still buy CFL's?

I have even replaced my halogen bulbs like the one you pictured with LED's.

While CFL are Not available in many stores now but people still have them installed or in storage expect to use them.

Sim to CFL before, LED still have problems & more so on older things or buildings like can't be dimmed even when LED/CFL label say dimmer works. Other Light Controls like "Eyes" to detect "night time" & IR "switches" to detect people often won't work w/ LED.

Even when not a dimmer or other "bad" controls, LED has problems & not just enclose fixtures. I put 4 GU10 7 watt LED to replace 50 watt Halogen last summer and already 1 LED Died but OE Halogen have run 15+ years in same fixture. I've just replace the Halogens for watts used & heat.

Almost All Real Cree LED "bulbs" first sold under $10 @ HD some years ago have died even in fixture that rarely used. Had 1 "3 way" Cree bulb of same format that died in < 90 days so @ lest could return to HD. Next version Cree "Bulbs" got cheaper and many died too.

Currently even many Main Stream Brands like GE Osram/Sylvania etc have Overdrive the LED to make units cheap for them & fail soon to keep selling new product.

All of my dimmers are Insteon. I have been using them for maybe 15 years and have only had a couple of failures. Insteon dimmers work on PWM and every bulb I have used works without issues, from standard incandescents to halogens and now LEDs.

They are managed by a UD eISY which runs on openBSD.

I used to have some LED failures with the earlier bulbs, but the only failure I have had in the last few years has been in an old ceiling fan, and that is a heat issue because of bulb orientation and lack of airflow. Someday, I will replace that fan but I am a practical guy and as long as something does what it is designed to do, I am in no hurry.

Also yes "standard" screw in "Edison" base bulbs may have same problems calling for Base Up or Down too.
Examples:
The filament or support(s) if have any may care. Many standard or halogen don't last long when the base is sideways too because no support of the filament to mount this way.
The base can have "weak" glue holding the metal to the glass. Many Halogen in Type A & other glass formats have extra problems because of things like extra heat they make that can affect even Bulb Cement/"Glue" used by good brands. ("fun read" web search "Lamp Capping Cements" )
