More modern LED chips are th 5630 and 5730 chipsets, and these seem to not only have more Lumens per chip, and emit them at wider angles.
The 5050 SMDs are Dated now and the market flooded with them and their smaller predecessors.
Radially firing LEDs do not seem to utilize the reflector properly and having the flat panel versions aimed properly is the ticket.
The 5730 or 5630 LEDs are not yet widely used in lighting for interior uses but more so for vehicular Exterior signal lighting, but an LED in an housing designed around a filament light source is questionable in ultimate result.
LED chips can be driven harder or less so, to produce more/less light, so direct comparisons by number of chips alone is not wise, not even from the same 'store' brand name or manufacturer.
