How long do COB LEDs last?
Using COB LEDs as Grow Lights
|Light Type||µmol/j (ppf/w)||Lifespan|
|COB LED||1.8-2.5||30,000 – 60,000|
|Double-ended HPS||1.4-1.8||10,000 – 15,000|
|Ceramic Metal Halide||1.1-1.5||15,000 – 20,000|
|High Pressure Sodium||0.8-1.7||9,000 – 17,000|
Is there anything better than LED lights?
XED or Xenon Energy Saving Discharge Lamps are superior to the most popular LED or Light Emitting Diodes in many ways. XED lights are better in terms of spectral contents, power consumption as well as total running life hours. They produce less glares and are clearer under foggy weather.
What is better cob or SMD?
SMDs are more efficient than COBs because the light source produces higher lumens per watt, which means that they produce more light with a lower wattage. They produce a wider beam of light which is spread over a greater area.
Are COB LEDs dimmable?
Dim-to-Warm is COB LED which works like halogen lamp when dimmed. Its specialty is that when you dim it the color temperature gets warmer. Usually dimming does not affect the color temperature of the LED. … It’s perfect for space where you want to have dimmed and warm toned atmospheric lighting.
How efficient are COB lights?
This improvement is said to deliver an energy savings of approximately 11 percent compared to the prior product generation. This series is available in four light-emitting surface (LES) configurations and can operate over a broad current range.
Does a COB LED need a driver?
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.
Are COB lights safe?
It is recommended to leave a space for cooling. Most of the LED bulbs come with a warning of using the bulb in the fully enclosed fixture. Our bulbs are rated as safe to be used in the enclosed fixtures for both commercial and industrial applications. You just have to keep in mind that you should leave some space.
What is the purpose of COB light?
COB lights are essentially an array of LED chips that are tightly packed together and bonded to a substrate such as silicon carbide. In effect this creates one large LED chip that has excellent uniformity of brightness, thus making it ideal for photographers and filmmakers.
