<r>Been using 12V constant-voltage supplies for LED strips. New client wants high-power COB LED modules for a bright storefront.<br/>
<br/>
COB datasheet says "700mA constant current" not "12V". Confused.<br/>

<r>Sign client wants color-changing logo, 5 meters of WS2812B RGB strip. Looking at controllers.<br/>
<br/>
Datasheets confuse me:
<LIST><s>[list]</s>
<LI><s>[*]</s>Controller says "100W max load"</LI>

So 5m strip * 18W ...

<r>Sign shop question. Customer wants 4ft channel letters, 60 white LED modules.<br/>
<br/>
Each module datasheet: 0.72W @ 12V. Total: 60 x 0.72 = 43.2W.<br/>

Do I size PSU at:

WS2812B IP65 strips work, marami akong na-install. PH humidity ruins them after 8-12 mo. Silicone tube fogs, water gets in.<br/>

Tagal na nito! Sayang hindi ko nakita on time. Set ko na sa calendar reminder for the next 11.11, bulk pricing on LED strips and PSUs ang aabangan ko for the signage shop.

Sa next sale, can you post here naman in advance? Mas convenient para sa mga regular bulk buyers like me.

Anong specific items po yung sale na 12.12 niyo this year? Bulk discount may available?

Need ko mag-stock ng LED strips for Q1 deliveries. Kung mura na ngayon, mag-stock na ako para sa next year's projects. Para sa signage shop ko, regular na po ako bumibili from circuitrocks.

<t>May small business po ako ng custom LED signage sa Pasay (yung mga 'Open' signs, channel letters, etc). Hindi po ako engineer pero years na akong nag-iintegrate ng controllers, drivers, at dimming systems. Bulk-buyer ako of LED strips and PSUs, so may decent feel ako sa supplier game. Open to ...
