What 1STOPlighting sells and which discount fits your basket
1STOPlighting is a lighting specialist, and one of its ranges gets a code of its own: COMEBACK takes 20% off Cyan lighting products. For everything else, LIGHT20 is the one to try first. On a $600 fixture that’s $120 off, against $60 from the 10% codes. The flat $15 from RAK20 only wins on baskets under $75. Clearance beats every code at up to 80%, but it’s discontinued stock.
Using a 1STOPlighting promo code at checkout
Paste the code into the promo box in your cart before payment. It’s one per order, so no stacking a voucher on top of a discount code. When a code is refused, the usual reason is clearance or discontinued stock in the basket, which percentage codes tend to skip. Drop to CTP10 or NOWORRIES10 and see whether a smaller one takes. Free shipping over $49 needs no code either way.
FAQs
Can I use two 1STOPlighting codes on one order?
No, it’s one code per order. Pick the largest your basket qualifies for, usually LIGHT20 or INSIDER15.
Is there a discount that works without a code?
Three of the twelve offers apply on their own: free shipping over $49, clearance markdowns, and the free Preferred Customer Program.
All 1stoplighting codes on this page were verified in September 2026. Offers and terms can change without notice, and a code that worked yesterday may not today — always confirm the final price at checkout before you pay.
