Key Features:
- Secondary optical design: PPF: 16.8μmol/s, PPFD:97.91μmol/s/㎡ @ 1ft. Through the lens for secondary scientific light distribution, improve light utilization, give plants more supplementary light, and improve light bulb lifespan to 25,000 hours.
- Imitate the solar spectrum: Customize a more ideal full life cycle full spectrum supplementary light program, covering the entire visible spectrum of 400nm-780nm; Color rendering index Ra is close to 100, infinitely close to natural light, suitable for every cycle of plant growth, effectively promotes plant growth, and improves crop yield and quality.
- Patented COC technology: Chip on Ceramic, SANSI's patented technology replaces the traditional Mcpcb aluminum substrate with a non-conductive ceramic heat sink, and directly solder the LED chip on the ceramic heat sink, effectively reducing the system thermal resistance between the LED PN junction and the surface of the heat sink, resulting in faster heat conduction and higher product reliability, makes the SANSI bulb has higher light efficiency.
- Safe and Reliable: The lamp body is made of special ceramic material, and the flame retardant grade reaches V0; the reinforced insulation structure design, no risk of electric shock, is safer; the whole shell material reaches the WF2 anti-corrosion grade, which is more reliable and durable; low IR, less heat radiation, avoiding close distance exposure burns plants.
- Guarantees: ETL listed & CE certification, quality and safety verified, 5 years warranty.

Interesting
Format: Kindle
Can't say I agree with the author's analysis, but it is interesting to read something that is not laced with political correctness. This seems an honest assessment of how things are. I recommend it.

An unputdownable reading on all matters strategic!
Format: Kindle
Hew Stratchan has used a clear and lucid narrative style to throw light upon the otherwise drab subject of strategy, drawing upon his talent as an historian, contemporising it in the current global environment, and has presented a practical guide to understanding strategic theory and putting it in practice.

Format: Kindle
I think we need to get to know who our new leaders are going to be. This is one of the books on "Mad Dog"'s reading list. So far it has been very compelling and interesting. Having lived during the Colin Powell years and Bush years as a young impressionable youth to now see what was really going on and the thought behind it.

A good supplement to Clausewitz
Format: Paperback
This book is an excellent supplement to Clausewitz or Jomni or anything like that. It puts the parameters of strategy in the context of recent history. I liked that angle about it. You will get a new perspective on strategic thought through that for sure. I can't think of anything that does that for a reader. The nature of the material really would go over with readers who have a history on the topic and who work in the field.
The downside to me is how the book supplements other material. It has awesome chapters on various aspects of strategy like technology. I liked the criticism of US policy in the Middle East. The author has some great points. However, the book needs a connecting thread among these chapters. It never clearly defines strategy and why it could or does for a nation. If you are in some staff college studying strategy, this book is your ticket to an A grade.
