A brief buying guide for LED Strips:
When you want to purchase a LED strip you first should think about the type of lighting you desire. The most common types are:
- ambient light (self light, cove light, tv back light on the wall and so on)
- intense ambient light ( as above but with increased intensity for some common tasks as navigating a space, eating, conversation)
- general light (the light we need for most task in our home, shop or office)
- intense general light (also called task light, for reading, writing, office work, cooking or to draw attention to a certain area, object or architectural characteristic)
After you decide on the type of lighting you need, when you search for LED strips you should look at the following three characteristics:
- brightness per meter (luminous flux, measured in lumens)
- actual LED lifetime (as opposed to claimed manufacturer lifetime. In brief, if the LED is not a known brand, actual lifetime is in the 1000-5000 hours range)
- light quality, also called color rendering index, CRI or Ra in short

The LED branding game, LED chip vs LED light source
The LED branding game, LED chip vs LED light source
The brands in the LED market are:
And if a product uses LEDs from one of these brands it has a certain quality guarantee. Therefore, one of the most common questions buyers of LED light ask is:
"What LEDs are used in your product?"
If the answer is for example "We use Cree" then the buyer assumes the product is of very good quality from the point of view of the LED used. Wrong.
Such an answer is vague and it does not ensure the buyer of anything because a producer of LED lamps or fixtures might be using Cree Chips or actual Cree LEDs.
If we uses Cree Chips (see below where the Chip is inside the LED) it means he buys these chips from Cree and builds an LED with them at a 3-rd party. In such case, from our experience the quality of the LED light source is most likely substandard.
Only if the producer uses actual Cree LEDs, which we can find on the manufacturer website we can be sure about the high quality of the LED light source. Below, a picture of Cree XP-G 2.
