- Expensive to purchase
- Require expensive ballasts
- Expensive to operate
- Short limited life spans
- Hazardous materials
- Excessive heat
- Limited K values
After quite a bit of investigation I have come to believe there are two types that stand out
- Ceramic Metal Halide (CMH)
Neither is cheap to purchase and at this time LED is very expensive, but I just found components to build your own LED light bar which exhibit none of the problems I've listed above!
|A Standard LED Grow Light|
The components to build and equivalent 400W 36000 lumen grow light at less than 1/2 the cost!
This is just one of many LED K values that are available and a wider spectrum could be made by including other K valued LED Chips.
12V power supplies are very inexpensive thanks to the computer industry.
Total cost about $200
While searching for your components you may find some bulbs are listed in 'mcd' rather than lumens. Here is a converter calculator to help you design the grow light you wish to build.
