LED does not always translate into less heat. The harder you drive an LED the more heat it will make.
I recently purchased these for in my RV to upgrade the 12volt fluorescents. While they only pull around .7 amps they get warm enough that it's uncomfortable to keep your hand on them.
Price seems to be the driving factor in design. I have what is a cheap 60-watt equivalent LED hanging in a suspended light in the kitchen. After 10 minutes of usage, you can burn your hand on the base. There's a more expensive one in the bathroom that barely gets warm.
There's a huge difference in the workings of LED compared to an incandescent bulb. An incandescent is just a filament creating a short circuit that heats up and glows. An Led us to have circuitry to drop the voltage to where it's usable. If it's poorly/cheaply designed you're going to create heat.
I bought some other bulbs to replace the rest of the 12 incandescents in the RV, Off the top of my head I don't remember the Lumen output, but I bought two different levels. There was a 200-lumen difference.
Appearance wise they looked exactly alike. performance wise the brighter ones got noticeably warmer. Testing them I figured out that the brighter ones were running at a slightly higher voltage. Disassembling them I found they used the same LED, but the brighter ones had a lower ohm resistor in the circuit.
My conclusion is, don't buy cheap ones.
