Lamp SPD/TM-30/metrics for four EANs and solar charge controller efficiency sweeps, moved out of the web repo so measurement data lives in its own history.

Raw measurement data behind buildfor.life/comparisons.
This repo is consumed by buildfor_life_web
as a git submodule at apps/web/comparison-data. At build time the site copies it to
/data/comparisons/, where every file is both chart input and a raw download. Directory
names are the keys the site's device pages reference in their csv: front matter, so
renaming a directory here requires updating the matching page in the web repo.

Lamps are identified by their EAN barcode so results stay unambiguous across brands and packaging variants. EANs starting with 2 are retailer-internal barcodes that cannot be resolved publicly.
Provenance
- Lamps: HPCS-6500 integrating sphere, 230 V / 50 Hz, five consecutive readings averaged after stabilization. Instrument driver and TM-30 tooling: HPCS6500-py. Procedure: lamp test procedure.
- Solar charge controllers: automated MPPT testbench sweeps. Procedure: see the linked test procedure on the comparison page.
Data is published as measured; files are never edited after the fact. Corrections happen by re-measuring and replacing the whole device directory in one commit.
