Budget 5700k CRI 95 100w COBs [Items in Stock]

I wonder about that too. I think it can’t get any worse than the stock LED that originally comes with the flood light.

On a side note, I have retrofitted a 20w (in a 20w casing) and have it sit on my desk running 8-16 hours a day in a tropical climate for 9 months now. The light hasn’t seem to fade much from when it was first run.

I might be interested in 2. I wouldn’t mind a round one of a similar size.

Let’s count the number of people interested so far:

Here is the interest/order status:

5700k:

HONDARIDER: 2pcs
BlueswordM: (Seeing if other Canadians want it)
Tc418: 3pcs [PAID & Shipped]
XXX-Man: 1pcs

3500k:
HONDARIDER: 1pcs [awaiting payment]
adam7027: 3pcs [PAID & Shipped]

Did seller provide you with the continuous (i.e. every 30 minutes) data for the first 100 hours of those led’s ? What kind of bond wire they are using ? The fill is silicone or epoxy based ?

It’s telling the guy who has ben buying in China 250k bulb’s and flood lamps per month… ;). The big COB are the easiest for small batch production, but the trickiest for long time usage.

I have reached out to the manufacturer yesterday.

The LED I will be selling is Flip-Chip type. There will be no bond wires inside these LEDs. The filler is silicone based, as usual.

They are currently doing the light decay test for me. The result should be available in a few days.

Huh, that means better durability.

Nice.

Put me Down for 3.

nice, would place it in something like this if It could work. if the LED could have an Enclosure;

The LED uses the same mounting holes as this one.

However, the reflector and lens like this one can be a little tricky to install, since my LED won’t have any holes (like the generic 100w ones) matching the prongs of these reflectors.

Here is the reliability test data from the Manufacturer. They tested on their 80 CRI version though, but the difference should not be significant.

I would be interested in 1 5700k
