Turns out Home Depot now uses Philips 205w and 330w CMH AllStart lamps in the garden center sections. They are bright and the color rendering is superb! Have you seen them?
I have seen 70 watt and 100 watt pulse start with medium base in Home Depot...but funny thing is they tend to put it in the outdoor light aisle instead of the lightbulb aisles!
Here, I see Philips 100-250w MV, 50-400w HPS, and 100w-400w MH in the bulb section of HD. In the fixtures section I see chinese 50w and 100w MH bulbs in Lithonia packages.
My local HD sells a 70w MH yardlight but it costs $80 or so.
they also sell 175w clear mercs and 70w HPS lamps.
