Yield Lab 600 Watt HPS Bulb

This High-Pressure Sodium grow light bulb emits an intense yellow-orange-red spectrum light that increases fruit and flower volume. It is perfect for the flowering/blooming stage of plant growth.

Encourages High Yields

This is a high-efficiency bulb that emits a 2,100 K light at 90,000 lumens. This high-intensity yellow-orange-red light causes plants to produce more fruits and flowers and is ideal for use during the flowering/blooming stage of plant development.

Also Encourages Healthy and Dense Vegetative Growth

Yield Lab high-pressure sodium bulbs now emit 30% more blue spectrum light, which stimulates vegetative plant growth. You could use this bulb for all cycles of plant growth, although a metal-halide bulb would be better for veg. Alternatively, you could use this bulb in conjunction with a blue spectrum LED light.

Long-Lasting, UL and CE Certified

The Yield Lab HPS bulb has an expected life span of 14,000 hours, which is considerably longer than the average HID bulb.

Remember, keeping HID bulbs on for longer periods of time is not what causes them to burn out. Switching them on and off is the problem.

To get the longest possible life span out of your new bulb, make sure to never switch it off and then right back on. It needs time to cool off first.

Yield Lab 600 Watt MH Bulb

The Yield Lab Metal-Halide 600 watt HID grow light bulb emits an intense blue spectrum light that encourages rapid plant growth. It is perfect for the vegetative stage of plant growth.

Encourages Rapid Plant Growth

This is a high-efficiency bulb that emits a 5,500 K light at 61,000 lumens. This high-intensity blue light causes plants to grow quickly and is ideal for use during the veg/cloning stage of plant development.

Long-Lasting, UL and CE Certified

The Yield Lab MH bulb has an expected life span of 10,000 hours, which is considerably longer than the average HID bulb.

Remember, keeping HID bulbs on for longer periods of time is not what causes them to burn out. Switching them on and off is the problem.

To get the longest possible life span out of your new bulb, make sure to never switch it off and then right back on. It needs time to cool off first.

Yield Lab 600 Watt Slim Line Digital Dimming Ballast

This ballast can run any HID bulbs rated at six hundred watts, be they High Pressure Sodium (HPS) or Metal Halide (MH). Use a MH bulb during the vegging stage and a HPS bulb during flowering.

Hang the light around 16 inches from the top of the canopy. A 600 watt light will comfortably grow 4 to 6 good-sized cannabis plants and yield around 250 - 600 grams. 600 watts is the most popular size for smaller scale growers, since it is the most efficient of all HID lights.

Slimmer Design Means Lighter Weight and Cooler Operating Temperature

The new Slim Line 600 watt ballast has a slimmer design, which means a lighter weight and a larger surface area in relation to the overall size. With more surface area for heat to disperse, the unit stays cooler than larger models, but is still every bit as efficient.

Dimmable Ballast Saves You Time, Energy and Money

The dimmable feature on Yield Lab's 600 watt Slim Line digital ballast allows you to run your bulbs at 50%, 75% or 100% power. It also has a super lumen feature which boosts your total power to 115%.

Being able to alter the power output allows you to give your plants variable light intensity throughout the day. Yo can also reduce the lumen intensity during the early stages of plant growth and provide a higher output during the later stages.

You can reduce excessive heat during hot days and also for your own comfort whenever you are working beneath the lights, e.g. pruning or doing maintenance work to your grow area. The ability to lower light intensity also prevents burning your plants.

A dimmable balance improves your quality and control and ends up saving you time, energy and money.

The Yield Lab 600 Watt Slim Line Ballast Can Run Both HPS and MH Bulbs

No need to exchange ballasts or even flip a switch. Simply switch out your Metal Halide (MH) bulb for a High Pressure Sodium (HPS) bulb and easily go from veg to flowering. Or vice versa.

The Yield Lab 600 Watt Slim Line Ballast Runs Silent and Cool

The new Slim Line 600 watt digital dimming ballast is designed for heat dissipation, encouraging the flow of air through the unit. It also has large heat sinks and internal cooling fans that drive any heat out through the exhaust ports. This ballast runs cooler than ever and is also designed to operate silently, with no humming or buzzing.

Risk-Free Purchase

All Yield Lab ballasts come with a 3-year warranty and are UL, CE and RoHS certified. They include a spare fuse in case of a shortage and have protection features against short circuits, open circuits, ignition failures and overheating.

Yield Lab Air Cool Hood Reflector

The Yield Lab Air Cool Hood HID grow light reflector works with 400 watt and 1000 watt bulbs and ballasts, in addition to the 600 watt components included in this grow light kit. You can use it with both High Pressure Sodium (HPS) or Metal Halide (MH) bulbs and be sure it keeps temperatures down, whether you grow in a closet, a tent, a grow room or a warehouse.

Large 6 Inch Vents Keep Temperature Down

The air cool hood reflector has two large six inch air duct vents that combine with the glass insert to keep the inside of the unit well-ventilated. Sponge seals around the lens cover glass keep the fixture 99.99% airtight.

Air flow through the reflector is maximized, the bulb stays cool while in operation and your grow area is much cooler as a result, despite the potential of this fixture for incredibly high heat output. This saves you money and protects your grow light.

Maximum Canopy Penetration and Coverage

Yield Lab's air cool hood reflector has a domed design that focuses the light onto your canopy for maximum penetration. The four-sided aluminum reflector ensures broader and brighter coverage.

Easy Setup and Maintenance

The air cool hood reflector is easy to install and to maintain. Using the included instructions, assembly is a snap.

High-Quality Design

The Yield Lab air cool hood reflector is made from galvanized steel-with a white powder coating to prevent rusting. Quality is guaranteed by the manufacturer's 3-year warranty.
