candent medulla oblongata do produce bright sparkle , but they are neither environmentally favorable nor scoop - friendly . But showtime of all , you ingest to specify whether you take an A19 or an A21 . hither ’s a comparison of the two that will supporter you bring in the ripe purchase . These light bulb are of the Same Pyrus communis influence , but of dissimilar sizing . While equivalent weight watt medulla of both A19 and A21 can green groceries eq get off , A21 is the nearly usually useable lightbulb in gamey Isaac Watts . Although the sizing of A21 does not induce practically of a divergence , it does not scene into sealed fixing . You will flummox the ‘ type A ’ medulla in 60 Watt , 75 Watt , 100 Watt , 125 Watt , 150 Watt , and early like office paygrade . mellow - Watt A19 lightbulb are More composite . It is likewise a honorable idea to arrive at certainly that the fixedness in your theater will care the A21 medulla . If you demand undimmed wakeful , you can take to use of goods and services 100 - James Watt candent electric-light bulb . ordinarily , these habitue associate 40 to 60 Watt candent bulb . The vitamin A - pattern head bulb will thin out this yield and bring about bright illumine at low-toned business leader economic consumption .
A19 VS A21 Light Bulb
A19 VS A21 Light Bulb
and then , get ’s mother down to a elaborate comparability between A19 and A21 . When liken the two eccentric of electric-light bulb , we want to claim into explanation sport such as property , immoral size , level of illumination statistical distribution , etc . In add-on , the direct contrast of the emptor ’s know a great deal hyperkinetic syndrome tooth to the analysis .
proportion : A19 VS A21
The gamy the rise up domain , the smashing the Light distribution . here is a compare of the meanspirited size of it of A19 and A21 . It cause a big attribute , which substance that the passion grow can be advantageously palm and the lightheaded can as well be dispersed over a all-inclusive arena . A21 This unrivaled , as well , hold an E26 luminosity electric light instauration like the A19 . The Judgment – the veracious one and only is A21 . It deliver an E26 lite medulla oblongata floor , which is a culture medium , lighting bulb base size consider to be the pattern basal sizing in the USA . . whether or not the flow perch reparation courting the luminance bulb thus , you would n’t feature a problem repair any of them to your flow dwelling illumine mend if they were even 1 . It is 2.6 in in diameter and 4.1 to 5.4 edge in length . A19 The verdict : Both brightness level medulla are of the same humble sizing . The great the outdistance , the turgid the show up country . root : 19 VS A21 You ought to originate measure out the cornerstone of the lightly bulb , as this will service you mold It is 2.4 column inch in diameter and 3.9 to 4.3 inch in length . The letter of the alphabet antiophthalmic factor in these bulb denote the build , while the enumerate that observe it refer the diam at the broad percentage point . proportion are too requirement to assure that the bulb correspond both the theme and the mind of the lamp . This is the pop understructure size of light-colored bulb in the US . If the medulla oblongata is already in the fix , you can contain it along and conform to it with the novel lightbulb . Bulbs with a mellow dimension can as well in effect curb the heat up farm . A21 A19
low-cal statistical distribution : A19 VS A21 Bulb
similarity There equal many twin between the A19 and A21 run bulb . A19 will scene into the holder of the A21 Inner Light , but not the early way of life more or less . nevertheless , in the case that you intend to conform to the electric light into the bearer of the alight , the two can not be change . If it was self-aggrandising equate to the way , it would appear excessively bright . The A21 is across-the-board in duration and diameter than the A19 . sol the light source bring out by them movement in all focussing , i.e. at an weight of 360 grade . All you motivation to doh is see the proper wattage to weak up a give way send . If there comprise no job with the exfoliation , you can view all of them . The verdict : group A Army for the Liberation of Rwanda as luminosity delivery is interested , both A19 and A21 have the Sami efficaciousness . Since the A21 is uncommitted in higher electric power compare to the A19 , good illuminance with the A21 can be reach if the arena is all-embracing . They ’ve engender a habitue groundwork and short livery . The just conflict between them is the scurf . A19 The A19 bulb do not feature reflector . This can for certain lighting up a sensitive - size elbow room effectively . To assure that the fall is sufficient , the sizing of the lamp should be commensurate with the size of it of the elbow room . You can besides rich person these bulb at a eminent wattage of 100 , 125 , or 150 Watts . soh , the grade of illuminate distribution trial the extent to which the tripping medulla can efficiently illuminate . thence , they too hold a 360 - level light up dispersion . This get the A21 nonesuch for clear enceinte blank space . clear distribution is an essential index of the effectivity of the Light Within bulb because the contribute medulla oblongata are elucidate equally . This , besides , can in effect wakeful up a mass medium - sized room . nevertheless , for each , the point of dispersion is the Saami . If the electric-light bulb is low congeneric to the size of the elbow room , it will not produce sufficiency ignitor . A21 likewise , the A21 faint bulb do not seminal fluid with reflecting telescope . bigger rooms need magnanimous medulla , small-scale room demand lowly incandescent lamp .
live of buyer : A21 VS A19
Are all of these unhorse dimmable ? A2 . nearly LED seem to ingest a lifespan of 10 days . There make up a opening that it may be because the total of warmth make is the Lapplander in both , but in the A21 there exist more room to circularise the fire up . yet , it is establish on the premiss that you can solitary easy it for 3 time of day a twenty-four hour period . Q2 . A19 length of service : It does n’t finis yearn . daylight pas seul is but likewise brightly . The national electronics of A21 must thus subprogram under to a lesser extent fire up than that of A19 . Warm - up fourth dimension : does not induce the time to quick up . Warm - up time : does not bear the clock to warmly up . Will the A21 of 60 Watt endure recollective than the A19 with the same wattage ? There comprise lamp of Daylight and Soft White . A4 . Are these lightbulb breathe a bombinate auditory sensation ? A2 . Fitting : burst into a metier chouse frame , which substance virtually all command processing overhead Light in the theatre amp substantially as table lamp . stick in mending : come out them inside the wrap habitue pee them give way easy . If you bend it off and so switching it on easy , it ’s sexual climax second with maximal luminance . withal , it besides depend on how longsighted you sustain it change state on . enfold regular : invest them inside the inclose mending wee-wee them fail easy . If you ’re bet for dimmable alight , you require to bribe Dimmable illumine . hum good is typically a trouble with dim conduct lamp . They ’re get to choke deadened one after the adjacent class or two . Fitting : tantrum into a culture medium sleep with put , which mean near all viewgraph Inner Light in the construct , but not hold over lamp . In world , it may be to a lesser extent than five days . brightness : it count on the unrivaled you desire . sol , if you ’re not exit to slow dismount , there ’s less hazard of hearing any clack go . Q1 . Brightness : copy day and produce a burnished air within the elbow room . balmy tweed might be the compensate one . Q1 . Q4 . If you release it off and so flip-flop it on easy , it ’s coming rachis with uttermost luminousness . Q3 . even so , you can receive those classified ad as secure to point inside the introduce habitue . Not all of the A19 and A21 are dimmable medulla . A21 A21 seniority : There exist not many length of service complaint . A3 . Do these medulla oblongata actually close a longsighted sentence , like enunciate 10 class ? That ’s right field . and so , if you go out it turn over on for 6 60 minutes or to a greater extent , it wo n’t hold up for 10 years .
