4.2 m 30 W subtropical all-in-one: standards language before the gel pack is frozen

An RFQ that only says “30 W solar light” will not freeze the gel chemistry or the seven-day autonomy logic. SOLARTODO LIMITED writes the published 4.2 m all-in-one — 30 W and about 4,500 lm, 54 Wp module, 210 Wh lead-acid gel — as standards language, not a price band.

4.2 m 30 W subtropical all-in-one: standards language before the gel pack is frozen

An RFQ that only says “30 W solar light” will not freeze the gel chemistry or the seven-day autonomy logic. SOLARTODO LIMITED writes the published 4.2 m all-in-one — 30 W and about 4,500 lm, 54 Wp module, 210 Wh lead-acid gel — as standards language, not a price band.

Phrases the annex should actually name

  • Pole: 4.2 m cast-aluminum shaft, 120 km/h project wind basis

  • Light: 30 W LED, about 4,500 lm, 12 h dusk-to-dawn

  • Solar: 54 Wp monocrystalline module

  • Storage: 210 Wh lead-acid gel

  • Autonomy: 7 rainy days under smart dimming, not 30 W flat-out

  • Architecture: all-in-one pole-top assembly (panel, battery, controller and LED in one housing)

  • Refs to cite: IEC 62124 for stand-alone PV logic; IEC 60598 for luminaire safety

  • Write: “meets IEC 62124 / IEC 60598 design language” — never “certified”

What compliance means on this gel SKU

The 210 Wh gel pack is the economy storage choice on this page, not a 2,000-cycle LiFePO4 claim. A naive 30 W × 12 h load is 360 Wh; the seven-day figure only holds if dimming cuts average draw to roughly 12–18 W. Name that schedule in the annex — for example 100% / 60% / 30–40% across the night — so bidders cannot swap in a smaller pack and still claim seven days. The 4.2 m height fits lanes, campus edges and low-speed access roads in Cambodia and the wider Southeast Asian subtropical belt.

Compared with a 150 Wh LiFePO4 20 W garden head, this sheet trades cycle life for a larger 210 Wh gel reserve and a 30 W, 4,500 lm class. It is the wrong annex for a 12 m 60 W split roadway package or a Sky Hub hangar pole. Ask for IEC 62124 / IEC 60598 wording and the dimming profile that produces the seven-day claim. No prices.

Buyer FAQ

Is gel the same as the LiFePO4 pathway pack? No — this page specifies 210 Wh lead-acid gel.

Must the annex name the dimming curve? Yes — otherwise the seven-day autonomy cannot be scored.
