LED Downlight Housing Cutout Size Guide — 55mm to 200mm
The ceiling cutout is the hole you cut to mount a recessed downlight. Get the cutout size wrong and you face one of three outcomes: the housing won’t fit (too small), the housing falls through (too large), or the bezel doesn’t sit flush against the ceiling surface (visible gap). This guide covers cutout dimensions across […]
Die-Cast Aluminum vs Steel vs Plastic Downlight Housings — Material Comparison
The material of a downlight housing determines three things: how well it dissipates heat, how long it lasts, and what it costs. This comparison covers the three materials used in LED downlight housings — die-cast aluminum, steel (stainless or cold-rolled), and plastic (PC or PP) — with specific data on thermal performance, durability, and cost […]
What Is a LED Downlight Housing Kit? — Understanding the Component That Holds Your Light
A LED downlight housing kit is the physical enclosure that holds the LED light source, driver, and optical components inside a ceiling. It is not a complete luminaire — it has no electrical circuit, no active LED chip, and no driver included. It is a passive aluminum shell with associated optical and mounting hardware, designed […]
What Certifications Do LED Downlight Housing Kits Require? — A Component-Level Guide
LED downlight housing kits are components, not complete luminaires. CE (LVD + EMC), UL, SAA, and ETL all apply to finished luminaires — products with an active LED source and electrical driver. Housing kits are passive aluminum enclosures with no electrical circuitry. They fall outside the scope of these directives. Published: September 4, 2026 | […]
Don’t Trust Unverified IP Ratings on LED Downlight Housings
Some small workshops claim IP44 or IP65 on their LED downlight housing listings without providing any testing documentation. Independent testing data suggests that over 60% of such claims from unverified sources fail when subjected to standard ingress protection tests [1].

What Does IP20 Mean for LED Downlight Housings? — Indoor Rating Explained
IP20 is the most common ingress protection rating for LED downlight housings used in indoor dry environments. It means the housing is protected against solid objects larger than 12.5mm (such as a finger) but has no protection against water. For residential living rooms, hotel corridors, office ceilings, and retail spaces — where downlights are never […]
COB vs SMD LED Downlight Housing — Which One for Your Project?
COB and SMD LED downlight housings differ in three key aspects: beam control, thermal performance, and unit cost. For residential projects under 12W requiring focused beam output, COB housings deliver superior beam uniformity with 15°–60° reflector-controlled angles. For commercial projects requiring 15W+ output over wide areas, SMD housings provide 120° native beam spread with better […]
