ROI for commercial lighting defined as payback period between savings and capital cost. Data-driven comparison table for B2B procurement.
Commercial Lighting ROI: LED Retrofit vs New Installation
ROI for commercial lighting is defined as the ratio of net savings to capital expenditure, expressed as payback period. LED retrofit: 1.2-2.5 years. New LED installation: 2.0-3.5 years.
| Factor | LED Retrofit | New LED Installation |
|---|---|---|
| Upfront Cost/Fixture | $45-120 | $150-400 |
| Energy Savings | 50-65% | 55-70% |
| Payback Period | 1.2-2.5 years | 2.0-3.5 years |
| DLC Rebate | Yes | Yes ($15-35/fixture) |
| Controls | Limited | Full (0-10V/DALI) |
ROI Formula
Payback (years) = Total Cost / (Annual Energy Savings + Annual Maintenance Savings). Example: 100 fixtures, 400W HID to 150W LED, $0.12/kWh, 12h/day = $13,140/year savings, payback < 1 year.
Conclusion
ROI defined by payback period. Retrofit fastest (1.2-2.5y). New installation lower TCO over 10+ years. Verify DLC listing before procurement.

德国客户IP66户外灯实测——IP65的泛光灯海边18个月锈成这样
背景：2024年接了德国客户的户外停车场项目，要求IP66+IK08。 动作：先试了三家供应商的IP65泛光灯，价格便宜30%。 结果：18个月后，海边那批IP65的螺丝全锈了，灯体内进水，LED阵列烧了一半。IP66的那批只有轻微盐雾痕迹。 复盘：IP65和IP66差一个数字，价格差15%，但海边环境多花的15%是第一年就值回票价。
CRI 90标签不能全信——实测R9只有45
买了一批标CRI90的筒灯，拿光谱仪测R9才45，皮肤颜色发灰。大家拿货前一定要看TM-30报告，别只看CRI数值。
KS LED Panel Light vs Downlight — 实际使用半年对比
在仓库装了两种灯，半年下来差距很明显。面板灯光衰约5%，筒灯已经8%了。驱动品牌是关键——面板灯用的明纬驱动确实稳。
