The ballast is packed neatly into an environmentally friendly cardboard. In the box, the ECG, 4 rubber dampers, an appropriate power cord and the manual is.
The processing of the EVG is absolutely clean. There are no edges or paint defects exist. Cartridges for the power outlet and the short cable with the connector to the lamp are of sufficient size. The switch for the power levels is nicely stiff and clean to use. An unintentional adjustment is actually almost impossible.
In test mode, the ECG ignites my MH and HPS lamps without any problems both with 400W and 250W.
The EVG "drives" the bulbs very quickly to their rated power (under 30 seconds). The lamps themselves do until he suffered a 1-2 minutes until the arc remains stable. This fast boot up I do not know of other electronic ballasts, the other electronic ballasts need much longer and drive the lamps slower and gentler on their rated power.
The ECG is also conditioned hot-restart capability. In sodium lamps the ballast is to start in a position the lamp mostly without delay again. For metal halide lamps, the device needs to get a few minutes around the bulb again. The EVG owned a smart ignition apparatus. This detects when the light bulb for a new start has not yet cooled down sufficiently and is doing only after some time a renewed attempt at ignition. This protects the lamps and the electronic ballast.
Basically, the electronic ballast ignites at a slightly higher voltage than usual. Normal ballasts ignite around 4.5kV, this ignites here with 6KV. This harms the lamps but does not reduce the duration to a possible restart.
As far as the positive characteristics of Lumii Digita 400th
Unfortunately, there are also a small dark side.
The 4 power levels are not all in the tolerance of the light source.
The level of 250W is designed to be much too weak at around 220W. The ballast used on the 250W level around 235W (calibrated meter). If you subtract around 15W for the TOE itself, remain around 220W for lamps left. In sodium lamps not a problem because around 12% less power is not a problem. For metal halide lamps, these 12% can however be already enough that shifts the spectrum and the lamp flickers possibly.
On the position 250W Boost allegedly the output is to be increased by around 10%, which is still in the tolerance of the light source is (the manufacturer). This should therefore be around 275W for lamps. Along with the power loss of the electronic ballast, the position should therefore consume approximately 295W. In fact, the electronic ballast used in this position than 330W, almost more than 100W to 250W of normal position. The lamp is so burdened with around 300W. This is both for NDL including MH lamps too much!
The lamps are overburdened with around 20%. This position is thus suitable to dim exclusively to 400W bulbs.
250W bulb would go broke very quickly on this position, and could even explode!
The two positions "400W" and "400W Boost", however, are in order. The position 400W consumes around 430W and 400W boost the position around 470W. This is both in the Toleranz.der lamps and can be used easily at NDL and MH lamps.
Of course, 400W lamps must be installed in these two positions.
In summary, that the ECG is ideal for NDL-250W and 400W NDL. For metal halide lamps, the Lumii Digita 400 is only suitable for 400W bulbs as an operation with 250W lamps due to the low output power in the 250W-position, can not be recommended.
The EVG is in Übrigem also an inexpensive alternative compared to expensive brand appliances for magnetic ballast in aquatics or terrarium. One disadvantage is not created by the except possibly guilty conscience because you saved money ;-). Qualitatively the Lumii is not worse than the brand appliances.
I give the device due to the low price 4 of 5 stars.
