| Drop-In Retrofit Process |
| 1 · Power-Down | De-energize the existing fluorescent troffer at the breaker |
| 2 · Remove Fluorescent | Remove existing T8/T12 lamps, ballast, and lens (existing ceiling cutout + junction box stay) |
| 3 · Wire LBLR | Hardwire LBLR retroⒶRCH-P1 directly to the existing line-voltage feed (120-277V universal) · no separate driver/ballast install needed |
| 4 · Set Dip-Switches | 3-WATTselect + 3-CCTselect dip-switches on the LED driver · field-set at install per spec sheet |
| 5 · Mount + Restore Power | Snap LBLR into the existing T-bar grid · restore breaker · verify 0-10V dimming + sensor function if /SRR or /SRT spec'd |
| Typical Time | 15-20 minutes per fixture for a trained electrician · significantly faster than full ceiling-tile pull + new construction install |
| Form Factor & Construction |
| Housing | SPCC steel housing + aluminum trim · lightweight retrofit construction |
| Diffuser | PMMA white back-lit diffuser · uniform light output across the full panel face |
| LED Array | Back-lit configuration (NOT edge-lit) · even brightness across the panel face · back-lit panels reduce hot-spotting vs edge-lit alternatives |
