What is PAR lighting size?
The most common sizes of PAR bulbs vary in size from PAR16, PAR20, PAR30, PAR36, and PAR38. LED PAR bulbs provide a dimmable, bright light that requires less energy to operate.
Breaking Down the Terms.

Then, what does PAR mean in grow lights?
Photosynthetically Active Radiation
Photosynthetically Active Radiation (PAR)
PAR is the waveband of light that plants use for photosynthesis. PAR is not a measurement of light, but rather represents the waveband in the light spectrum which is used by plants for photosynthesis. That's why we say, PAR is for plants.
In addition, what does PAR30 mean in light bulbs?
PAR30 LED Light Bulb | PAR 30 LED. What are PAR30 Bulbs? Parabolic aluminized reflector (PAR) 30 bulbs control light more precisely. They produce about four times the concentrated light intensity of general service A shape incandescents, and are used in recessed and track lighting.
Thus, what are PAR sizes?
The sizes of "PAR cans" tend to vary, usually ranging between PAR 16 and PAR 64. The number used to represent the size of the can is 1/8 of an inch, and this goes for the LED or regular bulbs as well as the PAR cans themselves.
Beside this, what is the difference between PAR-36 and PAR 46?
PAR-36 (PAR36) is 36 eighths of an inch in diameter or 4.50" (114.3mm) Maximum Outer Diameter.PAR-46 (PAR46) is 46 eighths of an inch in diameter or 5.75" (146.05mm) Maximum Outer Diameter.
Similarly, what is a PAR-36?
The "36" in the PAR-36 or PAR36 refers to the dimensions of the FACE of the bulb (or lamp) in eighths of an inch; thus a PAR36 is 36 eighths of an inch in diameter across the face of the bulb, 4.50" (114.3mm) Maximum Outer Diameter. "PAR" bulbs are usually but not exclusively halogen bulbs by design.
Eventually, what is a good PAR for a grow light?
Between 200-400 PPFD: This is great for seedlings, clones, and mother plants. Between 400-600 PPFD: This is great for early to late stage vegging cycles. Between 600-900 PPFD: This is great for the flowering, fruiting, or budding stage of plants.
Next, how much PAR do I need for veg?
The PAR intensity levels required during vegging growth are about half of the normal flowering requirements. We recommend a PAR level of 300 400 mols/m2/sec for your grow room. You can achieve these levels by reducing the power consumption of your grow light by 50% using a dimmer.
Still, can you have too much PAR?
Too much PAR (too much light) is wasteful and can even damage plants, although this is almost never a problem with artificial grow lighting.PAR also assumes that all photons outside of the 400nm-700nm range have no use in photosynthesis or for overall plant health.
Also, can I use PAR30 instead of PAR20?
PAR30, PAR20, and PAR16 bulbs are great replacements for incandescent bulbs but can easily replace other LED bulbs, such as BR (Bulged Reflector) bulbs. PAR Bulbs and BR bulbs are virtually interchangeable as far as the fixture, but the type of light they produce is much different.
Nevertheless, what is the difference between PAR 30 and PAR 38?
Now the bad news: PAR38 and PAR30 refer to the physical characteristics of the bulbs. PAR = Parabolic Aluminized Reflector, 38 = thirty-eight eighths of an inch, or 38*1/8"=4.75". 30 = thirty eighths of an inch, or 30*1/8"=3.75". As you can see, PAR38 has a larger diameter than a PAR30 bulb or can.
However, what's the difference between BR30 and PAR30?
What do the Numbers on PAR & BR Bulb Names Mean? Manufacturers use standard numbers like PAR30 or BR30 to indicate the bulb size. The number indicates the diameter of the lamp portion, not the base of the bulb. Notice that a PAR30 is the same diameter as a BR30 bulb.
