LTC Double Black Diamond v2 Built for Silent, Fan-Free Grow Rooms
At 228W input, the Double Black Diamond v2 delivers 21,300 lumens at 93 lm/W across a 6×4 ft footprint, drawing 1.89A on standard 120V service. 96 Philips Luxeon diodes hold a 5500K balanced white spectrum from 380 to 770nm — broad enough to carry both veg and flowering. It's a quiet full-cycle workhorse, not a peak-PPFD bloom fixture — best where silence and low maintenance outweigh max canopy output.
Fanless Full-Spectrum LED Grow Light with Philips Luxeon Diodes
Zero fans, zero moving parts — the over-molded aluminum housing dissipates heat passively. That means no fan failures mid-cycle and no noise in flowering rooms. Mount the 21-pound fixture on the included ratchet hangers and adjust height to match growth stage. The 110-240V input handles US and international service, with 5% THD at 120V keeping dirty power off shared circuits.
Key Features
- 228W Input / 21,300 Lumens: 93 lm/W from 96 Philips Luxeon diodes covers a 6×4 ft footprint with full-cycle white spectrum.
- Fanless Passive Cooling: Over-molded aluminum housing dissipates heat through its body — zero fans, zero noise, zero risk of fan failure mid-cycle.
- 5500K Full Spectrum (380-770nm): Balanced cool-white output with CRI 73 carries both veg and flowering without spectrum swaps.
- 96 Philips Lumileds Luxeon Diodes: Rated 70,000-to-100,000-hour LED life, long enough for several years of continuous-cycle production.
- 5-Year Manufacturer Warranty: Backed against electrical and LED defects, paired with a passive-cooling design that removes the most common failure point.
- 110-240V Input / 5% THD: Handles US and international service while limiting dirty power on shared circuits.
- Plug-and-Play Mounting Kit: Ratchet hangers with aircraft-quality cables and a 6 ft UL power cord ship with the fixture.
