Bulb information and specifications

Below are some tables compiled from data about various lamps so that you can compare and contrast different lamps yourself. Things to remember! Different sources of light have different light spectrums some better for plant growth and some not so good such as incandescent bulbs. Plant growth is heavily influenced by the amount and colour of the available light. Blue light at about 450nm favours root growth and intense photosynthesis. Red colours at 600 to 700nm stimulate rapid stem growth, intense flowing and chlorophyll production.
An interesting note about PAR watts and lumens for MH and HPS lamps is that the correlation between the two is over 97%. Meaning that for HPS and MH lights (remember the very restricted sample used here) on average there is less than 3% variance when estimating PAR watts from lumens. But remember that is an average and some lamps the difference may be much more.
If you have more information to add to the tables below PM Nietzsche.

The comment was made that this LED kit maybe equivalent to 150w HPS, maybe so. The growth is not making me too happy. I never had this many LEDs set up before and I thought it would be better this time, but no. Despite being older, the LED plant is not as mature as its two week younger sister in 400w HPS. It is two months for the LEDs now. Disappointing small results. I'm sure it'll get me stoned a few times. But really.
Here is my surprise point; the jars contain a goodly amount of manicured clean smoking bud material from the LED LowRyder2. It is just a fine smoke. Flushed with water for a couple days or so before the surgery. A rewarding ending. The HPS LR2 is still alive. Getting dank.
hello tngreen how are you. no scale but the count was pretty good compared to the HPS plant. The HPS put out a third more. THat isn't*much more.
Hey like thanx man. LEDs grow potent bud.
