Our LED kits come primarily from LED system integrators, particularly GELcore and SloanLED, both offering different kinds of LED lighting kits and each complete with its own power supply system. The majority of our LED use, as you'd expect, is with red. We also see occasional requests for other colors, however, most of them have a way to go to match the brightness levels and low cost that red offers."</FONT></P> <P align=justify><FONT style="FONT-SIZE: 16px">yY N2002t^ bN_YNuNLEDgqfNT bNTTy[7bQbNvNT Sbcev~z(u7b NShƋ6R FU0bNvLEDWYN;NegLED|~ƖbFUGELcoreTSloanLEDlQS NN:NbNcO N Ty{|vLEDgqfWYN kWYM gN蕄v5un|~ e/f~rLED ؏/fvQNrvLED NN[sNOb,g ؏0RN*NNNnavN^4ls^0 </FONT></P> <P align=justify><FONT style="FONT-SIZE: 16px">LEDs are deployed in two areas of channel letter lighting; the first is new signs where the preferred lighting source is LEDs. The second area is replacement for previously installed sign projects, where for reasons of cost savings, the sign owners have opted to change out the neon with an LED system. According to Zeck, "Most of our use of LEDs is putting it in the new channel letter signs that we build. Occasionally we have a retrofit request, and in that situation, we send out a pre-configured LED package of a preferred amount of LED lighting and a power supply to the sign distributor out in the field who then does the retrofit on site."</FONT></P> <P align=center><IMG border=0 src="/UploadFiles/Image/2017-09/YX_20170908161814544.jpg"></P> <P align=justify><BR><FONT style="FONT-SIZE: 16px">LEDN,r(WiWSIQW[v$N*Ngqf:SW-N,{N*N:SW/fhƋv;Ngqf:SSN*N/fN(uegfbcKNMR[ňNTv:SW :NNwb,g hƋ6R\OFUO bO(uLEDgqfegfbcyop0ncZeckN~ bN'YYpeO(uLED/f^(u(WiWSIQW[-N gePۏLN[v9eň (Wُy`Q N bNOSQN*NHQMnvLEDS 6qT\LEDgqf0R[ňs:WۏL9e 0 </FONT></P> <P align=justify><FONT style="FONT-SIZE: 16px">In one ESCO sign installation, a large Budweiser, closed-face channel letter project showed up on the shop floor, said Zeck. "This was a cursive letter style where each letter was about six feet tall and the total sign was about thirty-four feet in length with every letter populated with red LEDs. One benefit of using LEDs is you don't have to worry about corners or tight spots, especially with cursive fonts. The LED wire is flexible enough that you can bend it to follow the shape of each letter. Once finished, the Budweiser sign was lit up and we were happy with the results. There were no shadows or 'hot spots' on the sign face, and it was lit evenly between each letter."</FONT></P> <P align=justify><FONT style="FONT-SIZE: 16px">Zeck؏ bNf~6R\OǏN*N'YW ~vZ vhƋ  ~vZ vW[SO/fIfN ;`hƋ~ NASV:\ k*NW[k'Y~mQ:\ؚ W[k̑b&^ g~rLED O(uLEDvN*N}YY/f`O N_b_҉=NuSb_ yr+R/f[NIfNW[SO0LEDYup;m SN cgqk*NW[kvb_rۏLMT/_f te*NhƋ NOQsNUO4q_bўp W[kKNvIQN^8^GWS0 </FONT></P> <P align=justify><FONT style="FONT-SIZE: 16px">In another sign installation, ESCO has fabricated Arby's signs with neon lighting for years, but then the client requested using LED illumination for new signs instead. The change was emphasized for both a cost savings in energy consumption and also for the opportunity to reduce the servicing aspects of the signs. Since LEDs burn for an average of 100,000 hours before beginning to loose intensity and are less susceptible to breakage, the client, said Zeck, was willing to initiate a replacement in the signs lighting configuration.</FONT></P> <P align=justify><FONT style="FONT-SIZE: 16px">ddkKNY ESCOlQS؏6R NVW[S_ޏ^Arby svygqfhƋ Teg (WeArby shƋvǏ z-N [7bBlO(uLEDegNfyop NN:NO(uLED gHe0W~nTb,g Q\~O0Zeckh:y (WN*NLEDNTQsKNMR N,SNqp10N\ev[}T v^N Nf4x_c @bNegY[7b?aa(WhƋvgqfMn-NۏLfbcN0 </FONT></P> <P align=justify><FONT style="FONT-SIZE: 16px">"We installed the LED units into the Arby's letters, in both the hat band of the sign and in the channel letters, altogether it was about 200 feet of red LEDs per sign.

Now, customers have choices about how they want their signs lit said Michael Bluhm, National Marketing Manager for Direct Sign Wholesale. "When our customer chooses LEDs for a channel letter project, it's usually based on its energy savings considerations. We have a lot of LED projects coming to us from national accounts with significant amounts of electric signage on their properties and they see LED signs as a way to control energy costs and still have a great sign."</FONT></P> <P align=justify><FONT style="FONT-SIZE: 16px">ǏS [7b-viWSIQW[-NO(uvgqf/fyop s(W [7bSN gNf}Yv b0Direct Sign WholesalelQSv%~tMichael Bluhm S_bNv[7b bO(uLEDe 8^/fWNvV } bN'YYpeyv gRNy%ON ُNy%ONO~8^fehƋ Te NN_N w0RNLED/f gHe0Wc6Rnb,gvNye_0 </FONT></P> <P align=justify><FONT style="FONT-SIZE: 16px">"The most effective color for us is red and we usually use GELcore's Tetra product lines for our channel letter lighting. Occasionally other LED color requests come in as well. White is the second most quoted color, but it's quite a bit more expensive. Despite the higher cost, we occasionally get an order for white LEDs. In one instance, we had a sign that was a six foot oval logo, followed by fourteen 35-inch letters, all to be filled with white LEDs. Its design was no different than any other LED sign we've installed. We faxed the LED manufacturer the artwork which specified the size, style and font of the channel letters. They reviewed the drawings and determined how many LEDs were needed for each letter and that's how we populated it."</FONT></P> <P align=justify><FONT style="FONT-SIZE: 16px">Michael Bluhm bNuNvLEDNT-N [7b bO(u'YR/f~r vP\O bvQ[r }vr/f,{N'Y_(uvr FO/fb,gk50ǏSbN_0RǏN*N}vrLEDvUS /f6R\ON*N6:\-iWb_hƋ ASV*N35[W[k hQňn}vrLED (W6R\OMR bNHQߍLED6R FUlW[kv'Y\0</P> <P align=justify><FONT style="FONT-SIZE: 16px">LED lighting is definitely part of the future of channel letters as Bluhm of Direct Sign Wholesale noted, "We see a slow steady use of LEDs for our sign work.
