Lights for Kiez Burn 2021
Hi there,
i would like to discuss light with my fellow Kiez burners this year,
how will we organize lights,
since lights is not so far away from our area, i did request a quote from our power company,
so far we can rent lamps for 8,75 per lamp for the whole event, cables still need to be rented, but the prices are good, i expect we will pay less than 14 euro per lamp including all wiring, exact answer can be given in the next days
according to KB 2019 map, we will need 26 lights, my guess is that the map is incomplete, someone has contact data from lights lead last year to add to this documentation?
my wish would be to go solar and buy them, but I'm not sure if we can afford solar this year,
The lamps need to be:
IP65+ Certified (not in china, china doesn't deal with patents like we do and they are allowed to write on their product whatever they want)
The lamps need to be able to charge at daytime without sun and still provide enough light during the night (big battery capacity and big solar panel), the lights need to be able to run all night, not on movement detection mode (correct me if I'm wrong) again, the info on the package means very little in many cases,
the lights need to provide enough lumen (I'm sure somehow there is a german documentation stating how much lumen should hit the ground) the lumen need to be validated somewhere german patent laws count, china will put anything what sells on their product, and export sellers who buy from china often will follow these specs
The lamps need to be CE, here is a funny thing many people don't know, but it needs to be the CE Conformité Européenne, and not CE China export (watch out, individual sellers often swap them around so the internet has turned into a wild wild west where it can be hard to find something with actual CE Conformité Européenne )
The Akkus should preferably be exchangable, batterys dont last super long when not used, especially cheap ones
If the lamps are lithium ion, we need to have them charged around 50% when storing them for a year, storing them either on 100% or 0% will drastically reduce the capacity, especially 0%, so they will need a power indicator
-
The lights need to last for the whole event, and afterwards a year long in storage, higher quality comes at a price
If anyone feels like they have a great idea to make solar lights come true, i would be very happy, i personally will not further push this plan through this year

im happy taking the role actually, most of it is already done, at this point its mainly the practical part, which is very little,

Will you find a co-Realizer to enable the physical set up on Site for Build?

@Diarmaid if the lights dont get damaged and also don't lose their IP rating, (remain water proof, i don't see why it should be any problem,)
heat is with 10 watt leds not really something i expect issues with, for light transfer its definitely worth getting the right colour filter foil, anything else will have way bigger loss, with good filters you still lose around 2/3rd of the light (correct me if I'm wrong)
as an extra, we will probably still have some budget left to make things extra fancy

Thanks mareike for forwarding

Hi Bee, i would indeed be happy with someone helping with, or installing the lights, i dont have a clear vision yet on time consumption, thats why im very happy to get in contact with the realizer 2019

exactly, one very nice thing with having these lights on build is: we can during build use them to light up parts of the site for contruction
Answering your questions:
transport for power and lights is arranged,
i don't have a eta, i do have a eda though (estimate day of arrival :p) which would be Friday evening
06.08.2021 we can return them between 16.08 and 18.08, they are very relaxed with that
since its really a few lamps, i don't really see the point in redoing the lights map, we just place one and see how far the light goes and where it would be nice to have the next one

So I looked over the map from last year and there are only 24 lights placed there. There were some areas which I thought could have more lighting - e.g. it looks like there are no lights under the stairs, which were taking 2 lights at the Sommerfest stairs if I remember correctly.
We could also think about buying some lights, instead of renting them. With a budget of 1000, you can buy a good number of 100W LED floodlights - here is one for 36€ on Amazon.
You can also get coloured LED lights for a little bit more, here are some 100W ones for 45€ each.
If you drop down to only looking for 10W LEDs, then the price is also cheaper - here you can buy them for 16€ each, which works out at 800 for 50 of them.
What would be the cable situation? How long would the cables we need be, and could we rent them from the power company without renting any lights? Buying cables doesn't seem like it would be an option, to get a 50m waterproof extension lead looks like it costs about 90 euro, and the leads on the LED lights don't look very long.
Wait, these are solar powered, which means no leads required.

if you read my top post you can get a bit more info and the issues with amazon bought lights and solar panels,
i did a extensive search for buying lights, quality comes at a price,
the coloured lights are very cool though, maybe for example to light up the stairs?
around half of the budget for the lights goes into cables,
here is a breakdown based on 50 lights:
50 lamps : 375
50x40m cables: 225
50x schuko divider: 112,50
+19%MwSt
as the waylights are not only for decoration, they also have a safety function, they need to meet certain standards

@Diarmaid yeah as they are fairly bright its fine covering them up, their pickup location is close to Gotlieb-Dunkel brucke, if its doable for you to pick one up overthere, i can definitely ask,
Diarmaid · Thu 29 Jul 2021 10:53PM
Yeah I can pick it up from there.
