Hello, ceilsan32! The dual GasGlow LED illumination assembly adds $125.00 to price of the lamp. For example, the base price of the Model 2300: Westmoreland post-mount lamp head (includes housing, standard finial pictured with lamp, clear flat, tempered glass, and choice of finish) is $229.00. Adding the dual GasGlow LED illumination assembly increases the price of the lamp to $354.00.

We find that many of our customers gladly choose to make this initial investment in the energy-efficient illumination assembly, since leaving it turned on for 24 hours a day, 7 days a week, for one year is only estimated to cost approximately $11 per year, saving them hundreds to thousands of dollars over time. Additionally, it's expected to maintain its original brightness for at least 50,000 hours (that's 15+ years if turned on for 12 hours/day everyday!), and it provides the added convenience of never having to change a light bulb.

I hope this answers your question. Please feel free to contact us if you require any additional information.

Thanks!
