SOLARMAX 400W H.P.S BULB

German made high quality H.P.S. bulb.

As plants approach maturity they require less ''blue light" and more "red" light. The solarmax HPS lamps have been engineered to constantly deliver 10% more targeted "red " light energy to the maturing plants to promote strong flowering.

Solarmax bulbs put out more light than standard bulbs. This bulb has both blue and red spectrum so it is suitable for all stages of plant growth.

All Solarmax bulbs are manufactured in Germany by an ISO certified factory with over 40 years experience in HPS and MH lamp technology, ensuring high quality & optimised performance.

Solarmax bulbs are designed with the grower in mind.

55,000 lumens.

24,000 hours lamp life, although we recommend you replace your bulbs every 12 months as they lose 20% of their power in the first 12 months. This effect will not be visible as the lamps seem just as bright, but your plants will start to grow more slowly. We recommend to write the date at the base of each new bulb before installing it to estimate this lifespan.

Alternatively, it helps to write the date the bulb was put in on the bottom of the ballast.

Our best selling bulb. Tried and trusted by many. One year warranty.
