Phillips 600w Son T Plus Hps Bulb – Greenpower
The Son-T Plus has been the work horse of the European horticultural market for many years. We use these bulbs because of their high light output.
The Kelvin is 2100. 600 WATT = 92,000 LUMENS. Good working bulb too and comes recommended.
600 watt bulbs are the only size I tend to use because of their superior lumen output and durability. Its the choice of bulb for Professionals.
One of the most efficient and effective light sources available to indoor gardeners using magnetic ballasts, the Greenpower Lamp from Philips has a fine reputation for cultivating tremendous crops both in terms of quality and quantity!

On close inspection the advanced technology and robust design employed by a Philips Greenpower Lamp also gives you distinct benefits of increased reliability and longer lasting output at the optimum level. In other words, you have to change it far less frequently than alternative options! We recommend replacing this lamp every 6-9 months.
