What does CoC mean in photography?
In photography, the circle of confusion (CoC) describes a point of light directed onto a camera’s focal plane by the lens. Depending on the camera’s aperture, depth of focus, and field of view, the diameter of this dot of light might be extremely narrow when it hits the camera sensor, or it might be wider.

What are COB LEDs? Relatively new to the LED market, chip on board (COB) LEDs offer many advantages over the standard options. COB LEDs are basically multiple LED chips (typically nine or more) bonded directly to a substrate by the manufacturer to form a single module.
Is COB the same as Adobe?
Cob is a building material made out of clay-rich soil, aggregate, fiber, and water that is pliable and can be constructed into walls for buildings. Many people are familiar with a similar building material called adobe, which has many similarities, but a cob house does not use bricks or blocks as the adobe method does.
How long does a cob light last?
A COB LED has an average rated lifetime of 50,000 hours.
Do COB lights get hot?
COB LEDs are high-power components that therefore generate high temperatures. For example, the XHP70. 2 LED designed by Cree can utilize up to 28.8 Watts of electricity at 6V, which creates a significant amount of light and plenty of unwanted heat.
Do you need a driver for COB LED?
LED drivers are the handy little boxes that take the power from your electrical outlet and convert it to a form that the COBs can use. The electricity coming from your outlet is alternating current (AC), and this does not work for COB LEDs – they require direct current (DC) instead.
Where should I put my COB lights?
It comes under the downlighter category and is installed on to your ceiling. It is used for lighting up compact, narrow spaces that add to the decor of the house like most downlighters. The advanced technology used allows the LED COB to give out improved lighting as compared to other downlighters.
How do I know if my COB is LED?
COB LED technology is a recent advancement in LED lighting that allows for more effective energy use. As for COB manufacturing, it has several diodes on the same surface as SMD chip does. However, the distinction between them is that COB LED has more diodes. Typically, COB chips feature 9 or more diodes.
How many watts is a cob light?
Micro Width COB Continuous LED Tape
Typically requiring 8.2 watts per metre with an output of Approximately 710 lumens per metre on average. This slimline tape is bright for it’s micro size.
What is cob good for?
Cob is fireproof, while “fire cob” (cob without straw or fiber) is a refractory material (the same material, essentially, as unfired common red brick), and historically, has been used to make chimneys, fireplaces, forges and crucibles. Without fiber, however, cob loses most of its tensile strength.
How do you make a good cob?
Mixing Cob: Step By Step
Pour off the water from 3 buckets of clay, and dump the clay into the sand pile. Remove your shoes, and get stompin’. Every minute or so, use the edge of the tarp to pull and roll the material to more quickly incorporate the sand and clay. Add water if necessary.
