Off the shelf retail store screw-in LED and CFL bulb comparisons

[f-e]

I reckon that's bulging. The pic is just a little too 'side on' to really see. If the camera was just a bit higher you could see the Y indents better. It's about how the edges of the grooves catch the light. It's really very subtle sometimes. Here, it's about how the shrink wrap seems to be struggling to hold the disk down. The lip of the can here is very rounded, not nice and square. I reckon we have chicken dinner here.

No point taking more pics. Swap it out. You can bill me your time if I'm wrong

edit: Oh it is a 105, that's something.

I removed the capacitor and tested it with my multimeter. (I forgot that it can measure capacitors. Lol)

It was fine, it read 10 micro farad.

So I decided to plug the light in without the capacitor and it worked??

I ran for about 2 minutes, then went to a glow again.
I unplugged it, let it cool down, and plugged it in again.

This time it just kept going. After about 20 minutes, I unplugged it, let it cool, and plugged the capacitor back in, and it worked??
Go figure?

It was brighter though with the capacitor installed.


It's been running now for 20 minutes with no issues.
The temperature is reading 98°C on the aluminum circuit board on the backside.


So I dunno??



I think it was the temperature sense circuit that you mentioned, that was screwing up.



When it first burned out, (went to a glow) I unscrewed it, let it cool and tried it again and it was still just glowing, that's when I took the picture.

I threw it in garbage, then dug it out again to tear it apart to post some pictures.



I'm not really into SILs anymore, I just needed something to light up my window sill for a separate plant.

My strips are running at 6.825 Watts and put out 1195 lumens (not including the driver), spread out across 56 LED segments, so they are a lot more efficient, but the biggest thing for me is that they run off 19.5 Volts, so I don't have to worry about electrocuting myself or my plant.



PS... we used to blow up capacitors in school, just for shits & giggles.
They go off with a big pop and a whistle and spew toxic shit everywhere.
It was pretty cool. Lol

I remember when my teacher asked if anyone wanted to touch a 400 V capacitor.
The teacher was just kidding, but I volunteered.
I went all twitchy. Lol

I get it, but ngl it makes me sad to read that you don't use them anymore, especially after reading this entire thread.

Strange goings on with that cap. It still looks suspect but I have to presume the heat from de-soldering has played a part. There is next to nothing there.

I'm going to call it a result anyway. It works. Dunno why, but it works

There.

It's gone.

I will delete all my posts in this thread if you deem it necessary to the threads integrity.

What the hell did I miss? God damn it..

I have been left hanging to spidey.
If anyone tidies up, you can pull my now isolated posts to.

 

[blynx]

I had no problem with the any recent posts. PCBuds removed his posts himself.

 

[SpideyManDan]

Idk. Thanks to everyone I guess.

Amazing educational experiment. I'm still in the beginning pages looking for answers on how low can I hang a 50watt 5000 lumens bulb over my seedling. I'm not removing the cover just want some low light for a couple weeks before I turn on my 315cmh.

...looking for answers on how low can I hang a 50watt 5000 lumens bulb over my seedling.

It's better be at least 2 feet above your plant, or you'll cook it.

You can lower the light if the seedling is stretching too much, but you can damage your plant if the light is too close.
