Built for real outdoor abuseThe LED-8033E40C-G7 is a
screw-in post top retrofit designed to live outdoors, year round. Its 360° lamp body measures 7.8" in height and 3.4" in diameter, compact enough to sit inside most acorn, lantern and decorative post top housings. An
active cooling fan with dynamic temperature control pulls heat away from the LEDs instead of letting it bake the boards, which is what keeps output and colour stable over a long service life. The lamp is engineered to work efficiently in
enclosed fixtures and damp environments, and is protected against insects and dust — the two things that quietly kill outdoor retrofits.
Light quality and outputAt
4000K, this lamp gives neutral white light: crisper than warm 3000K, easier on the eye than cool 5000K, and excellent for security cameras and face recognition on walkways. With
5290 lumens from only
35W, it takes the place of a 175W HID lamp that has likely lost a good chunk of its original output over the years.
80+ CRI keeps signage, brick, landscaping and vehicle colours looking natural instead of the yellow-orange wash of old high pressure sodium.

Electrical and installationThis is the
347 volt version built for Canadian commercial and municipal distribution, and it also runs on 208V and 240V. The existing HID ballast must be bypassed so the lamp sees line voltage directly at the
E26 socket — standard practice for any
HID to LED retrofit, and work for a licensed electrician. Multi-directional mounting is a genuine feature here: install base down, base up or base sideways without affecting performance, which solves the awkward socket orientations found in older post tops and bollards. The
stepped dimming switch on the side of the lamp is set at install; choose "LO" for 50% output on low-traffic zones such as back lanes or overnight parking areas. Drivers are pretested, potted and burnt in three times prior to shipping, and the LED driver is USA designed and specified.
Where it works and what else to look atThink municipal streetscapes and sidewalks, condo and apartment grounds, hotel and restaurant entrances, school and church walkways, RV parks, cemeteries and strip mall lots — anywhere the decorative housing is worth keeping and only the lamp needs to change. For crews standardizing a whole site, the same platform is available as
35W post top retrofit EX39 4000K for mogul sockets, and in warmer or cooler light with the
3000K E26 version. For wall packs and shoe box heads on the same property, look at the
50W shoe box and wall pack retrofit 347V. The full
