Grow Light LED with full spectrum. SANSI led grow light imitate the solar spectrum, suitable for every cycle of plant growth. The SANSI 36W led grow light is designed for sprout, seeding, vegetative, budding, flowering and ripening growth stages. Compared to typical red or purple grow lights, it has high PPF and lens which can improve light utilization, giving plants more supplementary light,which is really suitable for high light plants like Jade plants, snake plants and String of Pearls.
Chip on Ceramic (COC) Technology
SANSI's patented COC technology 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.
Key Features
- The secondary optical design: PPF: 65.6 μmol/s, PPFD: 265.58 μmol/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, 2 years warranty.

A brilliant reassessment of Western intellectual history
Format: Kindle
"Liberalism: A Counter History" by Domenico Losurdo offers a brilliant reassessment of Western intellectual history. Dr. Losurdo is a leading Italian intellectual who has taught at university for many decades. Dr. Losurdo's book will interest readers desiring bold, thoughtful and compelling perspectives on U.S. and European history; with insights that may be very useful to us today.
More than anything else, Dr. Losurdo's work articulates a highly original and powerful critique of the ideology of capitalist property relations. Diving into the writings of John Locke, Adam Smith, Bernard de Mandeville and other influential Enlightenment thinkers, Dr. Losurdo explains that the principle goal of liberalism (used here in the European sense of the word) was to secure the rights of property holders over the poor; without the meddlesome interference of church and monarchy.
Readers who are accustomed to viewing U.S. history through rose-colored glasses will find their views severely challenged here. Dr. Losurdo persuasively argues that Thomas Jefferson, Benjamin Franklin and other revolutionaries enthusiastically embraced liberal ideology in order to help institutionalize its brutal slave economy. Put another way, it seems that Independence was ultimately about the prerogatives of the elite class who comprised the "community of the free" to buy, sell and own slaves. Dr. Losurdo goes on to explain how Americans put philosophy into service to justify Anglo-Saxon racial superiority and the violent dispossession of native peoples' lands.
Dr. Losurdo discusses how liberalism has influenced world history since the American Revolution. Through Dr. Losurdo's scholarship, we gain appreciation for the inherent tension that exists between liberalism's `emancipation' of the people who are privileged by virtue of their race and class; versus the `dis-emancipation' of the working class and poor who are comprised mostly of people of color. So, while liberals' greatest proponents have tended to use violence to lock in elite privilege (colonialism, the U.S. Civil War, the two World Wars), radicals have often struggled in the name of freedom for the people (the Haitian Revolution and the French Revolution).
Importantly, Dr. Losurdo challenges us to rethink the idea that progress is a natural by-product of liberalism. It is probably more accurate to say that liberals would be content to have the people live in misery; and that freedoms have been gained by ordinary people through struggle and collective action. The importance of this insight cannot be overstated. By compelling us to think anew about the liberal legacy, we can more easily detect the liberal apologists who pander for the one percent; while empowering the 99 percent of us to speak truth to power.
I highly recommend this outstanding book to everyone.

Excellent critical history
Format: Kindle
A very thorough and important work, astute view and scope of a history of a philosophy and its most sweeping consequences in the modern era. However, this also tends to be postcolonialism in a nutshell and is, from that view, an argument that goes back to at least the 1950s in academia and further if you're looking for straight up anticolonial voices of the past. Also I don't like the way the author cites sources, often giving the reader no clue as to the specific primary source being referenced, instead referencing an entire volume or a generic secondary source. Lastly, the book falls a little short as an interrogation of the marketplace itself.

Liberals run and cower, Losurdo is here to destroy you
Format: Paperback
First the physical product review:
The book came in a brand new condition with no wonky missprints or anything. Good quality paperback.
Now the contents:
This book is a complete vivisection of the liberal ideology. Losurdo takes you to the earliest foundations of the liberal ideology and lays bare in great detail its positions and internal contradictions. He studiously walks you through the evolution of the ideology within the context of the times to give the reader a full understanding of how the "great" liberal theorists of the time attempted to navigate the sociopolitical environment, and how their interpretations in turn affected (and continues to affect) the real politick. From the French Revolition to Nazi Germany Losurdo exposes the Liberal ideology for the exclusionary and exploitative sham that it is with Liberal theorists own words and liberal governments' historical actions. If you ever heard the expression "scratch a liberal and a fascist bleeds" this book will fully explain why. Truly a must read that I cannot recommend enough!

The subtle counterrevolution mixed into the liberal revolutions
Format: Paperback
From the time of Marx/Engels the critique of liberalism has always been set against the heroic tale of its association with the triumph of democracy. As the author here makes clear in close detail the history of the liberal framework is not so transparent, and this can be seen in the way the world of Locke emerges from the radicalism of the English Civil War with a liberalism that will condone slavery. This legacy is inherited by the American Revolution and leaves the whole onset of its democracy ambiguous. This is the classic 'bourgeois' revolution and is what lead to the critiques of the socialists who looked back at the inner failure of the democratic revolutions behind their surface success.

A Must read for all Americans and those who appeal to the American model
Format: Hardcover
Certainly everybody who uses the words, 'freedom' 'liberal' 'democracy', as so many do so loosely, and so many who appeal to the "New'World" model do, should read this; and then take stock of the double standards and hypocrisy that existed in the past, and which still thrive today, based on discredited myths from the past two or three centuries.
