[[File:Gluehlampe 01 KMJ.png|thumb|upright|Sarong bumbilya.]]
An '''bumbilya''' ([[Tataramon na Ingles|Ingles]] ''incandescent light bulb'', ''incandescent lamp'' o ''incandescent light globe'') iyo an [[ilaw|ilaw na de-kuryente]] na may kable na [[#Filament|filament]] na [[Joule heating|pigpapainit]] sagkod na iyan [[incandescence|maglaad]]. An filament nakakapalaog sa sarong glass bulb na kinaagan nin vacuum o inert gas tanganing protektahan an filament kontra sa [[oxidation]]. An kuryente pigsusyplay sa filament sa paagi kan terminals o mga kable na embedded sa glass. An bulb socket nagtatao nin mechanical support asin electrical connections.

An mga bumbilya pig-''manufacture'' sa sarong mahiwas na manlaenlaen na sukol, light output, asin [[boltahe]] ratings, poon kaidtong 1.5 volts sagkod kan haros 300 volts. Dai sinda nangangaipo nin panluwas na [[Regulator (automatic control)|regulating equipment]], igwa nin hababang [[manufacturing cost]]s, asin nagpupunsyon nin kasingmarhay kan [[alternating current]] o [[direct current]]. Bilang resulta, an bumbilya nagin lakop na piggagamit sa mga kaharongan asin commercial lighting, para sa portableng pagpailaw siring kan ''table lamps'', [[headlamp]]s kan kotse, asin [[flashlight]]s, asin para sa dekoratibo asin advertising lighting.

An bumbilya (Ingles incandescent light bulb, incandescent lamp o incandescent light globe) iyo an ilaw na de-kuryente na may kable na filament na pigpapainit sagkod na iyan maglaad. An filament nakakapalaog sa sarong glass bulb na kinaagan nin vacuum o inert gas tanganing protektahan an filament kontra sa oxidation. An kuryente pigsusyplay sa filament sa paagi kan terminals o mga kable na embedded sa glass. An bulb socket nagtatao nin mechanical support asin electrical connections.

An mga bumbilya pig-manufacture sa sarong mahiwas na manlaenlaen na sukol, light output, asin boltahe ratings, poon kaidtong 1.5 volts sagkod kan haros 300 volts. Dai sinda nangangaipo nin panluwas na regulating equipment, igwa nin hababang manufacturing costs, asin nagpupunsyon nin kasingmarhay kan alternating current o direct current. Bilang resulta, an bumbilya nagin lakop na piggagamit sa mga kaharongan asin commercial lighting, para sa portableng pagpailaw siring kan table lamps, headlamps kan kotse, asin flashlights, asin para sa dekoratibo asin advertising lighting.

An mga bumbilya bakong episyenteng marhay kisa sa ibang klase nin  de-kuryenteng pagpa-ilaw. Dikit sa 5% kan enerhiya na saindang pigkokonsumo iyo an pigko-convert sa nahihiling na liwanag; an natatada nawawara bilang sarong init. The luminous efficacy of a typical incandescent bulb for 120 V operation is 16 lumens per watt (lm/W), compared with 60 lm/W for a compact fluorescent bulb or 100 lm/W for typical white LED lamps.Vincenzo Balzani, Giacomo Bergamini, Paola Ceroni, Light: A Very Peculiar Reactant and Product.
