Energy, can't be created or destroyed,
Furthermore, in a LED we must keep the bulbs from overheating, to prevent or minimize any damage to its core chip to prolong its life cycle. Poorly managed heat can destroy an LED's light emitting capability. In this respect, a Helios with a higher efficiency produces much less heat than any LED light bulb that works at lower Efficacies. Energy, can't be created or destroyed, you can only transform to other forms, so where is all the energy is going when its not converted to light? "Heat" is the by-product that we don't want. The simple way to compare LED light bulbs is just by touching the bulb's heat sink after they have been working for 2 to 3 hours. You will know which bulb has the better Electricity to Light conversion rate.

So make the right choice from the beginning and don't buy inefficient light bulbs just because they are cheaper, in fact the better bulbs are always more economical in a long run. In Chinese they say "yifen qian yifen huo."
Next time when shopping for a LED light bulb ask for more lumens, and don't ask for more watts, ask for LED Helios from U-Tron and you will save yourself money and do a big favor to our earth by reducing your carbon footprint.
