Compare mining LED strips on a defined installed branch. Add compatible power equipment, cables, terminations, mounting, commissioning and planned servicing before deciding which quotation represents better value.
Normalize the two quotations first
Make a common bill of quantities and ask each supplier to identify what is included. Two prices per meter may describe different power levels, connection systems or maximum lengths. Compare an agreed lighting duty and approved configuration rather than assuming all products called industrial strip are interchangeable.
Keep requirements such as certification coverage and environmental suitability as pass-or-fail checks before the financial comparison. A lower price cannot compensate for a product outside the project's approval requirements. Record unresolved technical differences instead of hiding them inside a weighted score.
Use transparent energy assumptions
As an arithmetic example, 100 m operating at an assumed 8 W/m represents 0.8 kW at the strip. At 4,000 hours a year, that is 3,200 kWh before power-conversion and feeder losses. These are illustrative inputs, not ZBL product ratings. Replace them with measured system input power and the site's actual operating schedule.
Do not compare energy use without checking delivered lighting performance. Lower wattage is useful only if the required task visibility and other project criteria are maintained. Include controls and standby consumption where relevant, and explain the tariff assumption separately so the calculation can be updated.
Put service access into the cost model
Estimate how a failed section will be isolated, reached and replaced. Include the crew, access equipment and permitted work window. A slightly higher component price can be justified if it reduces replacement scope, but that claim needs a realistic maintenance procedure rather than a vague promise of reliability.
Model more than one scenario because failure frequency is uncertain. Compare a normal maintenance case and a more demanding exposure case. List spare availability, batch consistency and documentation quality as operational considerations. Avoid assigning precise savings to an unverified lifetime claim or assuming that every LED will last as long as its nominal rating.
Cost comparison worksheet
- Equivalent approved lighting duty and branch arrangement.
- Delivered equipment, installation and commissioning costs.
- Measured input power, annual hours and electricity tariff.
- Replacement-unit cost and labor/access assumptions.
- Spare availability and uncertainty in service-life estimates.
Questions buyers ask
Can a five-year warranty prove ten years of service?
No. Warranty coverage and service-life expectations are different statements with different conditions.
Should spare drivers be counted?
Yes, if the maintenance plan requires them. Compare both quotations using the same spare policy and compatibility requirements.
