Modern halogen lightbulbs allow their filaments to operate at a higher temperature than the filaments in standard incandescent bulbs. For comparison, the filament in a standard lightbulb operates at about $2900 \mathrm{~K}$, whereas the filament in a halogen bulb may operate at $3400 \mathrm{~K}$. The human eye is most sensitive to a frequency around $5.5 \times 10^{14} \mathrm{~Hz}$. Which bulb produces a peak frequency closer to this value?
