The reality is that those lamps that lasted longer… were dimmer. If you make them brighter (and whiter), they last shorter. That’s just the reality of using Tungsten.
What the Phoebus cartel did, quite boringly, is standardise the light-level/lifetime balance to 1000 hours. Quite openly too.
The Centenial light, hanging in a fire station in California, is running dim precisely to keep it from blowing
Here in Limpopo our rainy season is typically at it’s worst around Dec-Feb, I also get a bit gatvol after a week of dull weather, but I think you CPT guys have it the worst, at least up here it’s either cold, or wet, not both at the same time
My parents flew back yesterday, afer spending 6 weeks with my sister in Houtbaai.
In total, they only had 4 partial days of sunshine for the whole time
Has gotten so bad that I desperately wanted to add more panels, but when I see like 60w-230w from 5.2kw array for days on end, I know, deep in my soul, that it will be a total waste … and total overkill in summer, unless I can feedback from the Solis … stop scratching TTT!!! there is no itch … but … STOP!!!
Based on the measurements I have been taking in Gordon’s Bay it is not the highest rainfall for us and the 2014-2017 was also not the biggest drought for us in Gordon’s Bay.
So apparently it has come to light, them 2 power stations in Pretoria, been paying R300Mil per year… for 0kWh over the past 10 years! Expensive KFC and stellar ethics
Context for me: Very interesting to see that even with such a drive towards renewables already, still going in/up, yet it has no effect on Eskom’s inexorable slipping and sliding.
And then Sarel comes and drops this sommer on top of it all …
Well, here’s an interesting stat, I think. Numbers obtained from different sources, from 2015-2021 are CSIR numbers, before 2015 gleaned from news articles and assuming stage 1, etc etc. Numbers won’t be completely accurate, but it is close enough for the comparison.

So we’re quite close to beating “all load shedding from 2007-2022” this year.
What I found interesting listening to Brink saying Tshwane is behind with SSEG, but working with, yea, guess … CoCT(!) to get SSEG up and running again.
Man, I called it(!) … all Gauteng family, I implored them to just F&%^$ follow CoCT rules … trust me, it is coming to a city near you, I said.
Moving on, what is REALLY interesting, CoCT has now made it mandatory that you will only install an NRS-certified inverter if you connect to a DB with solar panels on top … interesting times for all those non-certified hybrid models out there, to eventually get them signed off.
to get outta here in CT
