The Worlds Most Powerful Single-Ended Grow Lamp! Consistently Tested Over 2,380 umol! (Verified By UL)

Must be used with high-frequency electronic ballasts (70-110kHz)

Par Pro 1,100 Watt HYPER ARC High-Pressure Sodium lamp delivers a staggering 2,380 umol on the Galaxy 1000 Watt Turbo setting! The HYPER ARC lamp has the ideal 2,000 degrees Kelvin Temperature for the best results during the fruiting and flowering phase. The industrial construction of the Par Pro HYPER ARC allows the lamp to exceed all micromole levels currently offered in a single-ended design. With attributes of long life, reliability and high efficiency, this lamp is an excellent choice for all indoor horticulture purposes.

Underwriter?ÇÖs Laboratories (UL) tested Par Pro?ÇÖs newest Hyper Arc 1,100 Watt lamp and said it was the most powerful 1100 watt single-ended HPS grow lamp they had tested in history. Consistently testing at 2,380 ??mol (micromole), the Hyper Arc is a 1,100 watt grow lamp that features a 400-volt arc tube and TT65 European glass jacket that generates 177,000 lumens! A remarkable breakthrough in horticultural lighting technology, the fact Par Pro has been able to produce this in a single-ended E39 lamp design will be a dream come true for the thousands of growers utilizing single-ended reflectors.

The Par Pro Hyper Arc?ÇÖs PBAR Flux is even more incredible, 2,688??mol! ?Ç£PBAR?Ç¥ refers to Plant Biologically Active Radiation which is measured from 350 to 800 nm in the light spectrum. This value recognizes that plants have photopigments other than chlorophyll that is sensitive to a wider range of wavelengths than chlorophyll is.
