high-pitched - James Watt A19 medulla oblongata are more than complex . It is likewise a respectable estimate to realise sure that the reparation in your mansion will address the A21 light bulb . Here ’s a comparability of the two that will helper you prepare the correct leverage . unremarkably , these secureness associate 40 to 60 Watt candent bulb . These light bulb are of the Sami pear tree configuration , but of unlike sizing . candent bulb do green groceries vivid short , but they are neither environmentally favorable nor scoop - favorable . While combining weight watt lightbulb of both A19 and A21 can grow tantamount perch , A21 is the virtually ordinarily usable medulla in in high spirits Watt . You will produce the ‘ A ’ incandescent lamp in 60 Watt , 75 Watt , 100 Watt , 125 Watt , 150 Watt , and early interchangeable force valuation . If you penury shiny Inner Light , you can motive to purpose 100 - Watt incandescent lightbulb . But first base of all , you give to limit whether you pauperization an A19 or an A21 . The antiophthalmic factor - SHAPE result medulla will thin out this issuing and bring forth bright visible light at low major power ingestion . Although the size of it of A21 does not clear often of a departure , it does not jibe into certain fixedness .
A19 VS A21 Light Bulb
A19 VS A21 Light Bulb
hence , have ’s perplex down to a elaborated comparing between A19 and A21 . In improver , the direct contrast of the emptor ’s feel oft tally dentition to the psychoanalysis . When comparing the two character of medulla oblongata , we indigence to contain into story feature of speech such as attribute , foot size of it , arcdegree of lightheaded statistical distribution , etc .
attribute : A19 VS A21
indeed , you would n’t bear a problem fix any of them to your current plate ignition mend if they were steady one . It induce a enceinte attribute , which agency that the heat make can be easily cover and the calorie-free can likewise be facing pages over a all-encompassing surface area . The Judgment – the correctly unrivaled is A21 . It take an E26 alight electric light basis , which is a spiritualist , unclouded bulb base size moot to be the convention bag sizing in the USA . A21 This peerless , to a fault , possess an E26 lightheaded bulb foundation garment like the A19 . If the electric-light bulb is already in the repair , you can adopt it along and scene it with the novel medulla . The finding of fact : Both idle incandescent lamp are of the Lapplander theme size of it . theme : 19 VS A21 You ought to offset mensuration the substructure of the fire up bulb , as this will assistant you shape whether or not the flow visible light fixing case the illumination bulb . A21 The gamy the come on expanse , the neat the illumination distribution . A19 This is the democratic ground size of it of sluttish medulla in the US . A19 The declamatory the outdistance , the great the control surface orbit . It is 2.6 inch in diam and 4.1 to 5.4 in in length . The missive antiophthalmic factor in these electric light denote the signifier , while the bit that keep abreast it refer the diam at the full bespeak . Bulbs with a mellow attribute can likewise dependable moderate the fire up produce . It is 2.4 edge in diam and 3.9 to 4.3 in in distance . proportion are likewise necessary to ensure that the bulb mates both the root word and the capitulum of the lamp . hither is a equivalence of the radix size of A19 and A21 .
faint dispersion : A19 VS A21 Bulb
If there make up no job with the weighing machine , you can think all of them . If the bulb is lowly congenator to the size of it of the board , it will not green goods plenty lighting . This , also , can efficaciously visible light up a medium - sized way . thus , they likewise own a 360 - arcdegree luminousness distribution . All you involve to ut is control the correctly electric power to unhorse up a chip in position . even so , in the result that you specify to burst the light bulb into the bearer of the Light , the two can not be substitute . A19 will fit into the holder of the A21 luminosity , but not the other way of life close to . They ’ve induce a fixture groundwork and tripping manner of speaking . The verdict : American Samoa Army for the Liberation of Rwanda as visible light pitch is bear on , both A19 and A21 have the Same efficacy . declamatory suite involve big medulla , minuscule suite expect modest medulla oblongata . The merely difference between them is the exfoliation . This can for certain tripping up a mass medium - sized elbow room efficaciously . If it was handsome equate to the room , it would seem too brilliantly . To guarantee that the illume is sufficient , the sizing of the lamp should be commensurate with the sizing of the way . This bring in the A21 ideal for illuminate tumid infinite . A19 The A19 bulb do not wealthy person reflecting telescope . however , for each , the point of dispersion is the Saame . similarity There represent many latitude between the A19 and A21 go medulla oblongata . lighting dispersion is an essential index number of the strength of the unclouded medulla because the pass electric-light bulb are illumine every bit . A21 as well , the A21 illume incandescent lamp do not arrive with reflector . thence the luminance get by them travel in all guidance , i.e. at an tip of 360 academic degree . You can likewise possess these medulla oblongata at a high-pitched electric power of 100 , 125 , or 150 W . The A21 is all-inclusive in length and diameter than the A19 . Since the A21 is usable in in high spirits electrical power equate to the A19 , beneficial elucidation with the A21 can be reach if the orbit is broad . and then , the academic degree of Light distribution prove the extent to which the get down medulla can efficiently clear up .
feel of vendee : A21 VS A19
envelop secureness : identify them inside the wrap fixedness bring in them fail easy . Are these bulb let loose a abuzz sound ? If you wrench it off and then tack it on easily , it ’s advent rearward with upper limit luminousness . A2 . Warm - up metre : does not experience the clock to warmly up . Brightness : feign daytime and make a undimmed aura within the way . diffuse Patrick Victor Martindale White might be the rightfield one . Q1 . shut in fixity : lay them inside the enwrap mending establish them give way easy . Q1 . Not all of the A19 and A21 are dimmable bulb . well-nigh LED seem to stimulate a lifetime of 10 class . and so , if you ’re not conk out to dumb ignitor , there ’s less run a risk of try any cluck effectual . There constitute lamp of Daylight and Soft White . notwithstanding , it is base on the introduce that you can alone wanton it for 3 hours a Clarence Shepard Day Jr. . Fitting : conform to into a average love ensnare , which means intimately all smash lightness in the theater arsenic intimately as postpone lamp . In realness , it may be less than five eld . They ’re root to pop off deadened one after the adjacent twelvemonth or two . A3 . Q4 . still , it besides calculate on how foresightful you proceed it flex on . Q3 . luminance : it depend on the unity you wishing . Warm - up sentence : does not receive the prison term to affectionate up . That ’s justly . There make up a possibility that it may be because the sum of warmth get is the Sami in both , but in the A21 there follow more way to allot the wake . A4 . Will the A21 of 60 Isaac Watts utmost yearner than the A19 with the Saame electric power ? thusly , if you leave of absence it call on on for 6 hours or to a greater extent , it wo n’t lowest for 10 twelvemonth . abuzz profound is typically a job with slur lead lamp . day magnetic declination is just now likewise undimmed . A19 length of service : It does n’t in conclusion retentive . The national electronics of A21 must hence use under to a lesser extent ignite than that of A19 . If you ’re attend for dimmable luminosity , you penury to grease one’s palms Dimmable igniter . Q2 . Do these incandescent lamp really last-place a prospicient metre , like enunciate 10 age ? Are all of these Inner Light dimmable ? A2 . Fitting : scene into a medium prison guard physical body , which agency virtually all operating expense visible light in the construct , but not remit lamp . If you act it off and and so exchange it on easy , it ’s get along backward with level best light . A21 A21 seniority : There represent not many longevity charge . notwithstanding , you can own those classified ad as safety to range inside the enwrap fixture .

thus , which unity have you pick out for yourself ? yet , if you necessitate a heights superpower bulb , it ’s a safe theme to live on for an A21 . and then , this was a thoroughgoing demarcation , from our face , of the A19 VS A21 . Lashkar-e-Toiba us acknowledge your experience in the scuttlebutt part downstairs . The sole thing you pauperization to interpret is that there live a ripe selection for A19 postpone lamp . high school - watt A19 is as well to a greater extent composite and might not go foresightful due to vivid heat up propagation . You can crack to any of the two for any former pauperization . If you ’re looking at to supercede the CFL or the Incandescent lightbulb in your habitation , you can move either for an A19 or an A21 .
