This is the BYGD that I bought from Amazon for $64.99. The link for reference only.

thanks for the pointers...

The cycle count estimate is based on a charge/discharge rate of 1C (the battery being depleted in 1 hr, and charged in 1 hr).
It is possible to discharge at that rate with a 300W inverter, but in most use applications you aren't doing that every cycle count. Also it will never charge at at rate of 1C. It will charge at about 0.2C. As such the life cycle rating until 80% is much much higher than 500 cycles. In real world usage, you will probably see more like 1500 cycles until battery degrades down to 80% capacity. In summary, the life cycle count scare of lithium ion power stations is completely overblown .
Yes, lithium ion phosphate cells will last much longer. But honestly, the BMS or inverter or charger controller will fail well well before the battery becomes an issue

Due to the explanation I provided above, battery cycle counts provided by power station companies are actually extremely conservative, not inflated.
Your story about your first LED light bulb is due to heat killing the bulb. Early LEDs (ie those big CREE ones) were notorious for overheating and frying themselves. Today's cheapo LEDs suffer the same problem. The more expensive LED bulbs today (ie not Great Value nor brown-box contractor packs) have adequate heat sinks to disippate the heat even when used in an enclosed light fixture.
