The shelf price may exclude suitable bulbs, fixed-wiring labour, mounting hardware, rural delivery or future replacement parts.
Start with the problem, not the product photograph
A successful purchase begins with the location. For The true cost of a Tiffany lamp, settle function, space, light and service access before motif and colour.
Photograph the proposed position straight on and from the side. Record the full dimensions, lampholder, bulb, connection method and the main task. A close product image rarely shows room scale, door movement or the angle from which a bare bulb becomes visible.
Three distinct decisions
1. Decide the job before the style
Build one total for the fitting, LEDs, compatible dimmer if needed, delivery, installation, safe mounting and foreseeable maintenance.
Keep this evidence: write the main task and the one constraint that could rule the fitting out.
2. Measure the real fitting envelope
Keep purchase, one-off installation and annual energy as three separate rows so unlike costs are not hidden.
Keep this evidence: record every dimension from one named reference point and photograph the tape measure in place.
3. Test the result from normal positions
Run the same calculation for two genuinely comparable models and verify what is included before judging the price difference.
Keep this evidence: repeat the check by day and after dark, using the bulb and furniture layout you expect to keep.
Worked calculation
First-year cost
C1 = P + D + I + B + E
Variables: P is product price, D delivery, I installation, B bulbs and E first-year electricity.
Example: For NZ$420 + NZ$35 + NZ$180 + NZ$28 + NZ$12, C1 = NZ$675. Compare the same complete scope for the alternative fitting.
The calculation gives a planning check, not an installation approval. Confirm the maker’s dimensions, use a full-size mock-up and let the appropriately qualified person decide structural and fixed-wiring details.
A real TiffanyLight.co.nz product as the worked case
20 cm Tiffany-style stained-glass wall light
A shallow wall fitting used to check projection, side glare, door movement and stair or hallway sightlines.
This model demonstrates the method; it is not an automatic recommendation. Draw its complete dimensions, verify the current electrical specification and test the proposed light in the real room. Product details can change, so check the live page before buying.
Confirm on the product page: total dimensions, weight, voltage and connection, lampholder, maximum wattage, included parts and installation conditions.
Practical New Zealand home scenario
Mark the base and shade footprint of 20 cm Tiffany-style stained-glass wall light in the proposed place. Use the furniture for an evening, sit in every normal position and check the switch, cable and passage. Only after it passes should you compare bulb requirements, included parts and full cost with another model.
Common mistakes
- Buying from an isolated product image without a full-size mock-up.
- Comparing price without included parts, delivery and installation.
- Choosing a motif before function and position are settled.
Final checklist
- The main use is written down.
- A full-size mock-up fits with margin.
- The bulb is hidden from normal positions.
- Dimensions, weight and connection are known.
- Complete cost and included parts are compared.
Record sheet: model, complete dimensions, total weight, voltage and connection, lampholder, chosen LED, position, mock-up photograph and check date. The current product information and maker’s instructions take priority over general guidance.
