Opticore Bulbs

[Hermila Farquhar]

Thestory is simple. Christmas lighting enthusiasts wanted better C7 and C9 Christmas lights with better color, less hot spots, and more durability. They wanted LED bulbs that could withstand the weathering, be usable for multiple holiday seasons, and still look amazing. So Wintergreen Lighting created OptiCore LED bulbs using the latest SMD LED technology combined with a remarkable polycarbonate lens to make stunning C7 and C9 lights for Christmas, holidays, and events.

OptiCore LED C7 and C9 Christmas light bulbs are the perfect choice for outlining rooflines, pathways, and landscape contours. These bulbs were built to look great even in harsh weather conditions, they'll last through many seasons of use, and they produce vivid light color that catches the eye even from a distance. Hang large C9 Opticore LED bulbs from your roof and outline driveways, walkways, and garden paths with smaller C7 LED bulbs.

OptiCore smooth opaque bulbs produce amazingly saturated color from base to tip for the vintage classic holiday bulb look. If you love your traditional painted incandescent bulbs, but want to make the switch to more energy efficient and long lasting LEDs, this is the bulb for you!

Opticore LED Light Bulbs combine the latest LED technology with a incredibly tough polycarbonate lens to create visually stunning, exceptionally durable C7 & C9 LED lights for Christmas, holiday, event, and landscape lighting use. With more saturated color, less hot spots, and greater durability than other LED bulbs on the market, Opticore&*reg; LED lights have gained popularity among commercial & residential holiday decorators alike.

C9 Light Bulbs are popular along roof lines due to their larger size and greater overall presence in comparison with other light types when viewed from a distance. C7 bulbs are smaller, but also popular for the roof. Additionally, C7 light bulbs are the ideal size for use outlining driveways, pathways, and flower beds.

Opticore LED light bulbs are available in a full spectrum of bright colors which leaves no limit to the creative possibilities you have when decorating for holiday or events. There are also two lens styles for you to choose from:

OptiCore smooth opaque bulbs produce deeply saturated color from base to tip for the vintage classic holiday bulb look. If you love the look of traditional incandescent painted bulbs, but want to make the switch to energy efficient LEDs, this is the perfect bulb for you!

The story is simple. Christmas decorating enthusiasts and holiday lighting installers wanted better C7 and C9 Christmas lights with more saturated color, less hot spots, and more durability.

OptiCore LED bulbs from Wintergreen Lighting are the state of the art for brightness, color, technology and durability. Thick polycarbonate lens walls are virtually unbreakable and saturate the lens with light and color. SMD diodes produce brilliant color at even greater efficiency than standard LEDs. When you want the best, OptiCore is your bulb.

The GE lights have sold out quickly the past few years, so if that happens again, we recommend the Christmas Designers T5 Smooth LED Christmas Lights (available in warm white, multicolor, or solid color). In our tests the multicolor lights looked as good as those from GE, while the warm white lights had a cooler tone that was a little further from the coziness of an incandescent.

Overall, we found that the wire quality has a lot to do with the success of a strand of lights. Some of the tested lights had tidy, close-knit strands of wire, while others were loose and messy. Some wires needed untwisting before use, like an old phone cord, and still others continued to accordion back on themselves no matter how we tried to stretch them out and lay them flat.

If by some chance the Christmas Lights Etc outdoor lights are unavailable, Christmas Designers sells nearly identical strands of 5 mm wide-angle bulbs in white, multicolor, or solid single colors that are a little dimmer but otherwise just as good.

We tested several white and multicolor sets from Home Accents Holiday, which Home Depot carries exclusively. The incandescent lights were fine but ultimately failed our durability test, leaving a large chunk of the string unlit after we submerged them in water overnight. The standard Home Accents LED Lights produced a nauseating flicker, especially when they moved. The Home Accents Holiday Smooth Mini Super Bright Constant On lights, discontinued as of 2020, glared painfully. Overall, the construction and wiring on all of these lights was sloppy and shoddy, and they just looked bad.

The box that the tested Brite Star lights came in goes a little lower, giving a number of 600 lights for an 8-foot tree (or 75 per foot). And this lighting calculator from Christmas Light Source indicates that 250 to 400 mini lights will light an 8-foot tree.

You have a couple of different ways to apply lights, but one method in particular gets a lot of praise. It involves putting the lights on from bottom to top, doing so vertically, going in and out as you move up. This technique puts the lights deep in the tree and creates depth and a warm interior. You can find more information from Real Simple. (If that approach sounds too radical, you can just do it the traditional way by circling the tree, working from bottom to top.)
