One of the biggest issues many cannabis growers face is dealing with heat extraction. Because LEDs increase environmental ambient temperature by only a º or 2, there’s less stress on the plants, and less expense dealing with heat.  Without the stress caused to plants by excess heat, LEDs make growing easier for a lot of beginner growers. Its just one less issue to have to deal with. An LED grow lamp looks very different from an HID grow light. Whereas the latter looks like an oversized industrial light bulb capable of kicking out a lot of brightness and power (which it does), the LED systems are self-contained boxes full of tiny bulbs. Each grow bulb is small in area and uses integrated optical components to shape its radiation pattern and reflection. It is important to note the direction of the light plays a big part in its usefulness. LED grow lights emit light at optimum wavelengths.

A good LED grow light provides almost only the spectra of light that the plant needs, with hardly any wastage. In theory this means bigger, better plants.

LED grow lights produce virtually no heat. This means that less investment, energy & thought has to go into dealing with heat extraction. Assuming that your grow room is located within your home environment, you probably keep the ambient temperature at around the ideal growing temps.


About LED Light Bulbs - Basic Information on LED Light Bulbs

LED light bulbs with high power LEDs provide long life. LED light bulbs offer clean pure white light and great colors! LED light bulbs are shock and vibration resistant, and LED light bulbs are direct screw-in replacements for incandescent bulbs.

Please read the information we have provided here on high power LED light bulbs to help you with selection of proper LED light bulbs for the task. The information helps you to understand what kind of LED light bulbs we offer, how the LED light bulbs you want operate with respect to light generated and how it is generated. Without this information, you will not know which LED light bulbs to buy, or if the led light bulbs you want to buy are the right LED light bulbs for you. Contact us at any time if you have questions.

1. LED Light Bulbs and Heat

High power LED Light Bulbs utilize the latest LED technology. These are the surface mount type or SMD LEDs. Small as they are, they generate high heat which must be dissipated or moved away from the LED in order for the LED to live the expected life time of 40,000 hours or more. To do that, most manufacturers have incorporated an aluminum or ceramic body with fins to increase the total area that the heat can escape to and be dissipated. The higher the operating current, the higher the heat load to be dissipated. That means more fins, or more thin and longer fins are required. In the case of one newly developed design, the LED bulb incorporates liquid to assist with the dissipation of heat.

Heat is the enemy of a LED. It can tolerate only what the manufacturer builds into it. Without the means to dissipate the heat created by the actual operating current applied to the LED to generate light, the LEDs will die a premature death. The high powered LED bulbs will have currents of 350-700mA plus running through them. Its a small amount compared to a standard light bulb. But, it is applied to a tiny piece no larger than 5/16" in diameter. This small section of material must take on 350-700mA which is huge for its size. This why so much heat is generated from so little electricity. There is no place for the current to go back to or to run to.

2. LED Light Bulbs - Color Temperature

The color swatches are shown to give you an idea of what the white light color differences look like. They are NOT the actual light colors you will see.

Color Temperature.

  • Daylight White LED light bulbs are generally between 5000 and 5500k.
  • Cool White LED light bulbs are generally between 4200k and 4500k Color Temperature.
  • Warm white LED light bulbs are generally between 2800k and 3300k Color Temperature.
  • The lower the number, the warmer or more yellow tint to the light will be visible.

Generally, warm white LED light bulbs look better in warm environments (earth tones for example) and daylight white LED Light bulbs look better in cooler environments (blues and stainless steel for example).

3. LED Light Bulbs - View Angle

The high powered LED Light bulbs are offered within 10° to 60° and wider beam width or view angle of the LEDs. The total volume of light between 20 degree view angle and 60 degree view angle LED light bulbs is the same. But, the concentration of light with narrower 20 degree view angle LED bulbs makes them seem brighter because you see all of it in a smaller space. The wider view angle LED bulbs will appear much less bright and that is because the same light volume has been spread wide. There is minimal light spread outside of the stated view angle.

4. LED Light Bulbs - Base Size

E27 is the designation for standard household medium base LED light bulbs. These are drop-in replacements for household sockets all over the world. E12 is the designation for candelabra base LED light bulbs. We also carry MR16 LED light bulbs and GU10 LED light bulbs. MR16 type LED light bulbs fit into two very small diameter holes in a flat socket spaced about 5cm apart. They will not fit into any other size MR socket. The same applies to the MR11 LED light bulbs, or other type LED MR light bulb. T8 is the designation for fluorescent tube replacements we carry. LED fluorescent tube replacements do not flicker.

When in doubt about the base size you need for your fixture, or if you need a special base size for a larger project, please contact us.

5. LED Light Bulbs - What does dual voltage mean?

Many high powered LED light bulbs will operate on dual voltage - 85vac to 260 VAC making them universally applicable anywhere in the world. Dual voltage means the led light bulbs will switch internally from 110/120 vac to 220/240 vac as is appropriate for the country it is used in. Voltage above 130 VAC will still have the potential to burn out the LEDs.

6. LED Light Bulbs - Specifications

The high powered LED light bulbs are listed with the watts that the LED is rated to consume. That changes a bit as the electronics also require power and effect the actual watts consumed. In general, electronics do not consume more than 1 watt total. We will also state the beam width or LED view angle, how many lumens and watts of light are generated by these high powered LED light bulbs, and a brightness comparison to incandescent light bulbs.

7. LED Light Bulbs - Warranty

ALL high powered LED bulbs have a warranty against defect. Defect does not include or mean excessive voltage coverage. Dual voltage means the bulb will switch internally from 110/120 VAC to 220/240 VAC as is appropriate for the country it is used in. Voltage above 130 vac will still have the potential to burn out the LED. Warranty does not cover installing the bulb in such a way that the heat dissipating fins are rendered ineffective. LED light bulbs are never to be installed in covered fixtures with no air circulation.
