1. Delhi starts replacing about 100,000 streetlights with smart LEDs
What happened. On 15 October, Delhi Chief Minister Rekha Gupta launched the replacement of about 1 lakh (100,000) streetlights on Public Works Department roads, starting with a pilot at the Moolchand underpass. About 45,000 of the existing lights are high-pressure sodium. The project, reported at about ₹473 crore and cleared in May, is to be rolled out over about four months. Each light connects to an app, a central dashboard and a control room that show faults in real time; a QR code on each pole lets residents see its details and report problems; and the lights switch and dim automatically with daylight. The reported specification calls for at least 150 lm/W, 3000 K, 35 lx on main roads and 25 lx on service roads. Contractors must keep 99% of the lights working and maintain them for seven years, and pay ₹2,000 per light per day if a fault is not fixed within 48 hours. The government expects about ₹100 crore in electricity savings over five years.
Why it matters. This is a clear example of where large municipal tenders are heading: high efficacy, warm colour temperature, individual monitoring, and a contractor who carries the maintenance risk for years, not just a supply price. Penalties per light per day make fixture reliability, driver quality and spare-parts logistics part of the commercial offer. For suppliers, it also shows the efficacy bar rising: 150 lm/W at 3000 K is demanding, because warm-white LEDs are typically 5–10% less efficient than 4000 K.

2. Lithium carbonate falls another 9%; LFP cells follow, slowly
What happened. InfoLink’s assessment of 14 October put battery-grade lithium carbonate at about RMB 109,000 per tonne, down 9.2% from InfoLink’s previous assessment at the end of September (about RMB 120,000), which itself was down 9.1%. Cells moved less: 100 Ah LFP cells averaged about RMB 0.420/Wh (−1.8%), and 280 Ah and 314 Ah cells about RMB 0.360/Wh (−0.7%). InfoLink expects lithium carbonate to fluctuate between RMB 100,000 and 120,000 per tonne in the near term, with continued downward pressure on 100 Ah cells from inventory and ample supply.
Why it matters. 100 Ah-class cells are the ones used in most solar street light batteries, and they are the format with the most downward pressure. For buyers, this is a good moment to insist on correctly sized batteries rather than accept a smaller pack to meet a price. When comparing quotations, check the usable battery energy in Wh and the date the price was set.

3. Aluminium holds near US$3,030
What happened. LME aluminium was about US$3,030 per tonne on 19 October according to Trading Economics, little changed from a week earlier. It remains about 7% below its level a month ago and about 9% above a year ago.
Why it matters. After the September fall, aluminium has stabilised for now. Housing and heat-sink costs for LED street lights, floodlights and high bays are therefore steady in the short term. The useful check for buyers is unchanged: compare heat-sink mass and the luminaire’s rated ambient temperature, not just the price, because that is where cost-cutting shortens LED life.

Frequently asked questions
What did Delhi specify for its smart LED streetlights?
According to reports of the 15 October 2026 launch, the lights must reach at least 150 lm/W at 3000 K, with 35 lx on main roads and 25 lx on service roads, connect to an app and central control room for fault monitoring, and dim with daylight. Contractors must keep 99% of lights working and maintain them for seven years, with a penalty of ₹2,000 per light per day for faults not fixed within 48 hours.
Are solar street light battery costs still falling in October 2026?
Yes. InfoLink's 14 October assessment put battery-grade lithium carbonate at about RMB 109,000/t, down 9.2% in a week, and 100 Ah LFP cells at about RMB 0.420/Wh, down 1.8%. InfoLink expects lithium carbonate to fluctuate between RMB 100,000 and 120,000/t in the near term.
