LED has Penetrating
None of Penetration force of xenon lamp or a halogen lamp is either good or bad. Xenon and halogen ,in fact, only two different lighting system(principle of lighting). This issue is just relevant to (k value).Because CT(color temperature) is constant value only K cares .Generally speaking, color temperature lower penetration power better. On the contrary, the higher the temperature penetration worse.

The color temperature of misunderstanding understanding, not temperature color (K value) is larger, the higher the brightness

This is the physical laws of spectroscopy: color temperature and brightness is inversely proportional . the higher the temperature, the lower the brightness
Please look data as follows;

4200K = 3500 Lumen = 372500 CD

4500K = 3350 Lumen = 362500 CD

5000K = 3200 Lumen = 352500 CD

6000K = 3000 Lumen = 332500 CD

7500k = 2900 Lumen = 332500 CD

8000K = 2800 Lumen = 312500 CD

10000K = 2750 Lumen = 300000 CD

12000k = 2600 Lumen = 282500 CD

14000K = 2500 Lumen = 262500 CD

Ranging from 3000K to 20000K LED color temperature on the market
European Union have strict rules for LED color temperature. the highest color temperature is not more than 5000K.The relationship between the color temperature and light color are probably as follows:

3000K- golden yellow;

 

4000K- yellow with white;

 

5000K – white;

 

6000K – white slightly with blue;

 

8000K- blue;

 

10000K- violet.
