What do you mean when we say Flood light?
versus a normal bulb (#3 in the image below for the usual snow cone type configuration). Beam angle is usually 165 degrees or less
flood lights have a narrower beam angle. Typically used for high ceilings or if malayo ang subject sa light. Longer reach but with large dark area behind and to the sides of the bulb. The lower the beam angle the sharper and harsher the shadows will be
I'm scouting for a good LED bulbs that will put for our ceiling. Ano recommendation sir?
very infrequently used, indoor, will not be left alone : any cheapo chinese LED bulb. Since there is a chance of bulb failure and fire must not be left alone for a long time. Since its much cheaper (I have 5watters that cost 80 and 40 pesos) the return on investment is sooner even if less frequently used and less lumens per watt. Also since infrequnently used
Used for a long time per day: therefore lumens/watt is of primary importance, GES specially the new models na 100 lumens/watt but you will sacrifice beam angle since the new ones have the traditional snow cone configuration. Typically 165 degrees or less. Older models may have 90 lumens/watt
For normal use, try to get a wider beam angle even if you sacrifice lumens/watt. Firefly even numbered wattage bulbs are cheaper than GES and have lower lumens/watt but have a large 220 degree beam angle. Larger beam angle, less harsh shadows
GE and phillips are more expensive and have less lumens per watt. They have basic and more advanced models. Basic models are usually snow cone configuration. GE has a staff of sauron configuration with a large beam angle. Expensive though. Their only redeeming feature is probaby lifespan
