LumenLedger

LumenLedger is a mobile + web app that helps homeowners and landlords manage every light in a property like an inventory system. You scan a bulb/fixture barcode (or snap a photo), log socket type, wattage/LED equivalent, color temperature, and install date, then the app reminds you when it’s likely to fail based on typical lifespan and usage. It stores receipts and warranties, so you can actually claim replacements instead of rebuying. For multi-room homes or small rental portfolios, it generates a shopping list that matches exact specs to avoid the common “wrong bulb” problem. It also supports quick room-by-room audits before move-out or inspections. This is not glamorous, but it’s practical: fewer emergency trips to the store, fewer mismatched bulbs, and less wasted money on duplicates.
