Well as you know I got my old 150 W HPS light going again. I did some research and found that the lamp will use almost as much watts as my 430! .....

How much power does my lamp really use?
Is this worth it?

Also I looked at a chart .... they go by PAR ... (PAR Watts objectively measure the total watts of Photosynthetically Active Radiation (PAR) emitted by the lamp. It accounts for the nutritional value and is a direct measure of light energy available for all-important plant photosynthesis)... and it doesn't go as low as 150 only 250.

Here are some snips of what I found ...

Lamp Efficiency In PAR WATTS
Efficiency Chart

WATTAGE -- COVERAGE
1000 watt - 4 to 5 feet across (1.3 to 1.5 meters)
600 watt - 3.5 feet (1 meter)
400 watt - 2.5 possibly 3 feet (.8 to .9 m)
250 watt - 2 feet (.6-.7 m)
175 watt - small, less than 2 feet

According to this last chart I would still need more light since my space is 3x5 .... but I don't use all that space .... part of it is a shelf where the fan sits.

But will it be worth the cost .... I mean 372 watts to operate a 150W lamp!
