none of which seem to be useful if you don't go outside
but okay
Yeah it's not useful if you don't leave the house
unless you're like me and abhor ringtones
Anyone done LED strip+those extruded aluminum diffusers for lighting? Trying to figure out how best to get the aluminum to align well.
Piece of wood behind it
In optimal angle for wanted lighting angle
Kinda regret not just getting a 12' board and flattening it out and glueing the aluminum on.
I was worried about heat, but they're fucking LED strips, they don't generate shit for heat.
I've got those little clips up that the aluminum snaps into.
2x50w led with passive cooling generates barely 80c heat on casted light thrower(material of cast==chinknium)
Led strips.. Maybe +3c ambient
Worst temps come from the transformer/powerblock
I specced everything out for worst-case and then totally missed all the reasons that would never be an issue.
I mean as long as you dont use +5 meters on single line
Its all okay
It's like 4x 3m lines.
what spacing per meter
What do you mean by spacing?
Leds per meter
!answer 0.025*120*3
9
9A per 3 meter*
Wut
It's 12v, and 18w/meter
That's not 9a
A number was missing
Oh single colors so probly not 25ma per led
!answer 0.02 * 120 *3
7.2
Each of 4 runs is only using around 4.5a, power supply can do around 25a in peak-for-this-area-ever temps with zero cooling, 40a in why-would-you-visit-texas-in-the-summer heat if it's just mounted on a file cabinet to sink heat, each run has a 12AWG cable for power. So it's a bit overspecced.
That's why I regretted caring about the heat with the aluminum, since it didn't matter.
Do 2835s really suck only 6-7mA
When they are single color
These are also $90/5m Yuji LEDs, not $3 generic Aliexpress rolls, they might just be more efficient
Doubt as smd leds usualy take up to 60mA to produce white light afaik on any sane lumen scale (25+) at their usage voltage (3.3-5)
It's 1000 lumen... It doesn't specify is that's per roll or meter though
So they're probably just dimmer. Usually high-CRI is.
If its per roll of 5 meters
