COB LEDs are an integrated package. With less spacing between the LED chips , a much wider surface can be covered by the COB LED’s light beam with less glare. CRI is increased due to the wider beam angle.
What is the difference between LED and COB LED?
The SMD LED light source is a single patch LED lamp bead with a light-emitting diode directly attached to the surface. COB LED light source packaging technology is a direct chip package on the board, COB has improved light efficiency, improved glare effect of LED lights, and reduced light loss.
What is better cob or LED?
But the difference between LED light COB and SMD is that COB LEDs have more diodes. COB chips typically have 9 or more diodes. … Another aspect of the COB vs SMD LED Lights difference is in the use of energy. COB is known for better lumen-per-watt ratios and heat efficiency.
What does COB mean on LED lights?
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.
How long do Cob Lights last?
As a result, a relatively small and lightweight lithium-ion battery pack can power a COB LED based light system for very long periods of time. In fact, our 6W COB LED Trade Show Light will run 14-15 hours using our very small and light weight (1.25lbs) rechargeable Mobile Power Center.
Why are COB LEDs better?
Advantages Of COB LED Chips
These are the biggest advantages of COB LEDs for growing: Higher light density: many small diodes in a tight space makes for a much higher light density, meaning you need less space to produce more light.
Do COB LED need heatsink?
In the case of COB LEDs, it is possible to directly attach a COB LED to a heat sink (see Figure 2). As a result, COB LEDs do not require PCBs in order to install LEDs into a luminaire and the subsequent reflow process is no longer necessary.
Is Cree LED best?
Unlike compromised bulbs, the new Cree LED® bulb delivers an even better light with better performance, a longer life and more energy savings. … It has an improved longer lifetime of over 27 years (30,000 hours), lasting as much as six times longer than some LED bulbs.
Are COB lights any good?
In other words: it is a great spectrum for plants in all stages of growth. The main issue I have is that the COB LED grow light chips are far less powerful and the lack of any additional diodes means the fixture as a whole is less powerful still. … But this light costs quite a bit less.
How hot do COB lights get?
The only data sheet I can find for these generic Chinese LED’s shows a max temp of 80 Deg C (176 F). I’m getting temps far higher than that. Possibly the LED’s are really efficient and pump out most of their power as light. Maybe I should be asking what the efficiency of an LED is.
Which brand of LED lights are the best?

Are COB LED lights 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.
Do COB LEDs need drivers?
To do it correctly, you use a constant current driver for each CoB or get as driver that with a high enough voltage (e.g. 80v or more) to drive them all in series with one driver. … Your supply is a constant voltage supply. They do not work well with LEDs.
How do you test a COB LED?
- Plug your black lead into the common input, and plug your red lead into the input marked with a “V” (voltage), “Ω” (resistance), or ANYTHING but an “A”. The input marked “A” is for measuring amperage, or current. …
- Switch your dial to DC Voltage, which is what LED drivers put out.
