These are nice bright C-9 bulbs. Definitely as bright as incandescent bulbs. They have a smooth glass bulb, Which is breakable. And they have 5 LED's in the center at filament height. Side-by-side, they are almost identical to incandescent C-9's. BUT the COLORS are what I'm here to talk about. They are just beautiful & with true color that you haven't seen on C-9's in years. I've been buying these now for 3 years, Slowly changing out the incand. for the LED to see how the held up & if they fade like the Chinese incand. that I've been getting from Lowes & Home Depo. (Almost clear within a 2 year run). These LED's: Blue are blue & Green are green. The incand. that I bought 3 years ago are identical clear now with no idea of the original color. The LED Red's & Amber are perfect matches. And I threw in a few purple & pink to add a little spice to the traditional color mix. I've done about 400 of the 500 plus around the perimeter of my house & garage roofs at $2.00 per bulb. Now I've got neighbors stopping & asking where I got them. They are the same C-9 lights in the same strands on the same roof line that I've put up for 39 years here, BUT the LED colors from Novelty have made all the difference in the look. And now I've got colors that pop & at a small fraction of the wattage cost. If they last like I hope to report later, I've found my answer to the junk light problem. Next year I will be back to buy Novelty's WHITE light socket strands so they match the white guttering & facials they are against (and be gone with those aggravating plugs & fuse holders--cheap junk). Buy them, You won't be disappointed.p.s. I would like to see that free shipping again through AMAZON.Thanks for listening to my raving.UPDATE Jan. 2020Had a few bulbs get water inside (They seem completely sealed) , But NOVELTY more than took care of the problem & all is good in the world again. EXCELLENT company to work with. Still looking Beautiful years later. Caution: glass is fragile, But I wouldn't want plastic that will fade in the sun.UPDATE: Dec. 2024These C-9 LED's from Novelty have turned out so great, That I changed out my indoor real tree to Novelty C-7 LED's. They have 3 LED's in each glass bulb & Are exactly like old c-7's except the colors are BRILLIANT year after year. No fading, No HEAT, No hot wires, No ridiculous electric bills even with 250 on my 8 foot real tree.As for these C-9's outside, The price has dropped a little & They still get that "WOW" from passer's by. I did change out to white wires & sockets Cut-To-Fit & They blend into the white gutters & facials with no plugs & fuses along the way. It makes installing them quick & easy on brass hooks in minutes. Go with NOVELTY LIGHTING for Professional results.
