Boulder Lamp PerfectPar 650W Full Spectrum LED Grow Light

The Boulder Lamp PerfectPar 650W Full Spectrum LED Grow Light combines commercial-grade output, broad canopy coverage and precise lighting control in a slim six-bar fixture. Designed for controlled-environment horticulture, it delivers a carefully balanced full spectrum across coverage areas of up to 25 square feet while drawing approximately 640–650 watts, depending on input voltage.

• Power: 650W Full Spectrum LED
• Coverage: Up to 25 Sq. Ft.
• Design: Six-Bar Light Array
• Control: Dimmable to 10% + Controller Ready

Rather than concentrating output in the center of the growing area, the six-bar architecture distributes light across a large footprint. BoulderLamp’s published PPFD map for a reflective 4’ x 5’ grow tent at a 12” hanging height shows a center PPFD of 1,130 µmol/m²/s, with strong distribution throughout the measured canopy.

The PerfectPar 650W supports 120V, 208V, 240V and 277V electrical systems and can be paired with BoulderLamp’s programmable lighting controller for automated schedules, continuous intensity adjustment down to 10% and advanced lighting recipes.

Built in the USA using components from established lighting manufacturers including Philips/Signify, Osram, Cree and Samsung, the PerfectPar 650W is designed for dependable operation in grow rooms, greenhouses, vertical farms, tents and other indoor horticultural environments.

Full Spectrum Horticultural Output

The PerfectPar 650W delivers a broad full-spectrum output designed to support plants throughout the growth cycle, combining blue, green, yellow, orange and red wavelengths rather than relying on a narrow-band output.

This broad spectrum lets one lighting platform stay in place as plants progress through different stages of development.

Up to 25 Square Feet of Coverage

The six-bar configuration spreads output over a large canopy rather than concentrating it directly beneath a single central light source.

BoulderLamp rates the PerfectPar 650W for up to 25 square feet of coverage, making it suitable for large indoor growing areas as well as single and multi-tier commercial installations.

Published 4’ x 5’ PPFD Performance

BoulderLamp’s published PPFD map gives a detailed look at distribution inside a 4’ x 5’ reflective grow tent at a 12” hanging height. Measured PPFD values include:

• Center PPFD: 1,130 µmol/m²/s
• Inner measurement points: approximately 1,009–1,055 µmol/m²/s
• Intermediate measurement points: approximately 727–753 µmol/m²/s
• Outer corner measurements: approximately 456–468 µmol/m²/s

Actual PPFD will vary with hanging height, reflective surfaces, room configuration, fixture settings and other environmental factors.

Slim Six-Bar Architecture

At only 2.2 inches high, the PerfectPar 650W keeps a low-profile design despite its large footprint. Its overall dimensions of approximately 45.4” x 47.2” x 2.2” spread six LED bars across the growing area while minimizing the vertical space the light itself occupies.

That is especially useful in environments where available height needs to be carefully managed.

Premium LED Components

BoulderLamp builds the PerfectPar series with components from established manufacturers. The PerfectPar 650W incorporates LED technology from Osram, Cree and Samsung, paired with Philips/Signify LED drivers.

The fixture is manufactured in the USA as a robust lighting platform for both home and professional horticultural environments.

Programmable Lighting Control

The PerfectPar 650W can be paired with BoulderLamp’s optional programmable lighting controller for more advanced automation. With the compatible controller, growers can:

• Turn fixtures on and off automatically
• Maintain daily lighting schedules
• Adjust light intensity
• Program settings day by day
• Create week-by-week lighting programs
• Adjust lighting throughout the growth cycle
• Set and manage Daily Light Integral (DLI) strategies
• Use optional pulse-mode operation

Dimmable to 10%

The fixture can be dimmed down to approximately 10%, providing substantially more control than a fixed-output grow light as lighting requirements change.

Optional Pulse Mode

The PerfectPar 650W supports optional pulse-mode operation for facilities incorporating advanced lighting-control strategies.

Multi-Voltage Commercial Compatibility

The PerfectPar 650W supports common residential and commercial electrical configurations, including:

• 120V
• 208V
• 240V
• 277V

Nominal input power stays close to 650W across the supported voltage range. At 120V, nominal input is rated at 650W and 5.5A; at 277V, nominal input is approximately 640W and 2.31A.

Choosing a Voltage Configuration

120V — for standard installations running on conventional 120V circuits.

208–277V AC — for commercial facilities with higher-voltage electrical infrastructure, drawing lower current per fixture.

Designed for Controlled-Environment Horticulture

The PerfectPar 650W suits several indoor and protected growing configurations, including:

• Grow tents
• Indoor grow rooms
• Greenhouses
• Vertical farms
• Single-tier cultivation
• Multi-tier cultivation
• Commercial horticultural facilities
• Controlled-environment agriculture

Broad coverage, slim construction, multi-voltage compatibility and programmable control make it adaptable to both standalone installations and larger lighting layouts.

Built in the USA

The PerfectPar 650W is manufactured in the United States and designed for demanding home and commercial horticultural installations.
