LTC Double Black Diamond v2 Luxeon LED by Philips Lumileds

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.
