Analyzing the difference between the G4 and G9 of LED lighting source

1 First, precisely, G4 and G9 refer to different led high bay light supplier (lamp beads) of the pin type, G is representative of two or more of the bulb socket pins, and this is used in the lamp bulb refers pins category; within the distance , behind standard method 4 or 9 or 5.3,6.35, etc. are referred to the center point between the prongs measure with calipers two pins together and divided by two outer distance after that can simply point the amount of just what a ruler than the amount of the feet of the center of what came out .4 mm and 9mm very far, just one volume to know.

2 Crystal Light for now mostly used G4 or G9, both of which the difference is very obvious that the most fundamental difference is that the G4 can only do low pressure, because the pins are too close, so if your lights are G4, then there will be the light of the ceiling plate transformer! G9 and now only do high pressure, that is, if your lights are the lights above the G9 will not have a transformer! the good difference.

3.G4 from the appearance of the two prongs are like needle like pins, of course, is also small compared to the volume of the bulb, and two pins G9 are like oval ring pins, not the same as the needle pins. Of course , the volume is also slightly larger.

4 For a regular manufacturers of lighting is concerned, according to national standards, regardless of which national standards are to be posted Watts label (or called lamp standard), the requirement is to be attached to the customer or to change the bulb installed when the bulb must be very easy to see the place, usually posted near the lamp. Of course, some manufacturers for many heads of crystal lamp where each class may not have posted, but also to at least one of the stickers. If one did not stick , then it 's just like you buy three products almost. If you look at the label, then what is written above volts? Because only do low pressure, and are generally made of 12V G4, and G9 for, because now only do high pressure, so it should be written about 220V.

5 Also, if you buy led high bay light supplier  attached was there, then you are as I said above, in addition to the distinction between the bulb above should be also printed a parameter marker fishes, such as writing a 12V 20W or write the 220V 40W, etc., on a word not see a light bulb can look at other bulbs words, if you do not print all the words that you buy quality lights too did not guarantee it. In fact, for G4 bulbs are also called JC bulb (refers capsule-shaped halogen bulbs).

6 Again, a reminder to buy replacement bulbs should note that in addition to the nominal model as outside lamp power also can not be greater than the rated power, such as G4 bulb is equipped with a transformer, if the replacement bulb larger than the rated transformer if it is not also bear, likely to cause the transformer burned.
