Got most of the parts for the 2540 build (4000k colour temp). I am still waiting for the 60W drivers so fired them up with some 50W units.

 

It runs super cool at 31C after 30min so hoping with the 60W drivers it will stay below 40C.

 

Forgive the 'raw' state of the build, but it has to be disassembled when the new drivers arrive anyway.

 

With all new parts (still have to buy fans) it works out to about $75USD and generates 13000 lux at 50cm (130W from the socket).

 

My 'go to' light is a full spectrum white 1500W COB unit (230W from the socket) and interestingly that outputs the same lux, but at 76% higher power usage.

 

In $$$ terms assuming 16hrs per day at 25c/kwh the 1500W unit costs $0.92 per day vs the 2540's at $0.52 - In theory the build will pay for itself in 267 days.

 

Might need to rethink the setup now ....

It's only when you look at an ant through a magnifying glass on a sunny day that you realise how often they burst into flames

Finally got round to tidying up the 2540 build with the new 60W drivers.

Using 165W from the socket at pf 0.98 and generating 15000 lux at 50cm.

Temps are 32deg C after 15min so I’m happy there’s some breathing space.

Latest incarnation from the lab ... :party:

 

1 x Meanwell ELG-240-C2100B driver

6 x Cree 2540's (4 x4000k , 2 x 5000k)

2 x NZXT 140mm fans

1 x 12V1A fan supply

A fair chunk of aluminium

Wiring, switch, 100kPot and other bits and pieces

 

Variable power from 25W to 250W

Lux - Not measured yet, but estimating around 22500 lux at 50 cm.

 

Cost to build around $150USD

 

Waiting on a descent power switch and still deciding on how I'm going to hang it
