4x Buyer Protection

Yield Lab makes the best 600 watt HPS bulb on the market in terms of value for money. It 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.
