sir, pansin ko sa mga ganitong floodlight na binebenta online. di nila sinasabi anong klaseng led smd ang ang gamit nila. sa mga nabili mo, ano sa tingin mo ang ginagamit nila?
Other than being surface mounted LEDs hindi po ako familiar sa type nila sir. But they did provide lifespan information on the package: Greenfield 25,000 hours, & Firefly 20,000 hours, and 80 lumen/watt & 90 lumen/ watt efficiency, respectively. Based on this I would surmise they were the high efficiency kinds of SMD LEDs.
@@wanderingandroid hindi ko nasukat sir. But again based on their published specs, a 20W Firefly terra LED floodlight has 1800 lumens, while a comparable Firefly 20W LED bulb has 1700 lumens. Magkaiba ang format nila kaya maging subjective ang visual impression kung ano mas maliwanag. But they both output similar luminous intensity.
Precio de lanpara, led, 20w
540 Pesos or about U$9.50

@@ramschannelreviews pero yung pagka 20 watts nila compared to other 20 watt bulbs or the likes. Kumusta naman po?
