How much can my client save in utility rebates?

Most US utility programs offer $1–$3 per DLC-listed LED tube. On a 1,000-tube project, that’s $1,000–$3,000 in rebates that directly reduce your client’s net project cost. We provide DLC product IDs and pre-filled rebate application forms for the top 50 US utility programs to streamline the rebate process.

What is your ballast compatibility guarantee?

We guarantee Type A compatibility with ballasts from Philips, GE, Osram, Advance, Universal, and Fulham — covering over 200 ballast models. If our Type A tubes fail on any listed ballast in a real installation, we replace the affected tubes free of charge. We also provide a ballast compatibility list for your pre-installation review.

Can you provide energy savings calculations for my project proposal?

Yes. Send us your fixture count, current wattage, and operating hours, and our technical team will provide a detailed energy savings calculation, annual cost savings estimate, simple payback period, and 10-year ROI analysis within 24 hours. This documentation is formatted for direct inclusion in client proposals.

Do you offer project-based pricing with extended payment terms?

Yes. For projects over 2,000 pieces, we offer project-based pricing with 30/60/90-day payment terms for qualified contractors. Net-30 terms available for contractors with established credit history.
